NFL Scientific Advisory Board Fact Sheet
Nov 15, 2018




In 2016, through its Play Smart. Play Safe. initiative, the National Football League (NFL) allotted $40 million in funding for medical research primarily dedicated to neuroscience. The NFL then assembled a Scientific Advisory Board (SAB)—chaired by Peter Chiarelli, U.S. Army General (Retired)—comprised of leading independent researchers, experts, doctors, scientists and clinicians to develop and lead a clear process to identify and support compelling proposals for scientific research to be funded.


Having awarded $35 million of the NFL's $40 million commitment, the league has developed an additional funding program (the "Program") to allocate $4 million to further medical research for the purposes of inviting research proposals and providing funding for innovative preclinical, translational and clinical research being conducted by leading investigative teams related to the prevention, treatment, rehabilitation, and return-to-play following injury to the hamstring muscle group. The remaining $1 million will be allocated at a later date.

The anticipated total amount to be funded for this Program is $4 million. The number of winning investigative teams, and the total amount to be funded, will be determined in part based on the quality of the proposals submitted and by recommendations from the SAB. The NFL will make the final decision as to which proposals are funded and to what degree based on the number of proposals recommended by the SAB. Read more about the Request for Proposals here, and submit your Pre-Proposal here.


The members of the SAB named for the 2020 funding opportunity were selected based on their expertise and background in medical research.

In addition to Gen. Chiarelli, members of the board are:

  • Ajit M.W. Chaudhari, PhD, FACSM – Professor, Division of Physical Therapy, School of Health & Rehabilitation Sciences, The Ohio State University
  • Brian Feeley, MD – Professor in Residence, Chief, Sports Medicine and Shoulder Surgery, UCSF Department of Orthopedic Surgery
  • Richard L. Lieber, PhD – Chief Scientific Officer and Senior Vice President, Shirley Ryan Ability Lab, Professor of Physiology and Biomedical Engineering, Northwestern University
  • Timothy C. Sell, PhD, PT, FACSM – Research Professor, Atrium Health Musculoskeletal Institute, Charlotte, NC
  • Lynn Snyder-Mackler, PT, ATC, ScD, FAPTA – Alumni Distinguished Professor, Francis Alison Professor


The goal of the 2020 Program is to provide funding support for research proposals from leading investigative teams in the field of the biology and rehabilitation of muscle injury, specifically hamstring strains. The NFL's intent through this Program is to demonstrate the potential for translational breakthroughs by leveraging innovative research, emerging science, current data sets and archival material related to the prevention, treatment, rehabilitation, and return-to-play following muscle injury, specifically, to the hamstring muscle group.

This Program's funding opportunity is intended to facilitate the following five lines of potential inquiry: 1) Original or ongoing basic translational research activities involving the use of biologic formulations (e.g. PRP, stem cell therapies, pharmacologics) in the treatment of muscle injury using the hamstring musculature as the injury model; 2) Evidence-based clinical research exploring the use of biologic agents in the treatment of sport-related muscle injuries; 3) Development of improved prevention and injury risk mitigation strategies specific to hamstring injury; 4) Design of rehabilitation and return-to-play strategies following hamstring injury that reduce the risk of injury recurrence (secondary prevention); and 5) Innovation (e.g. micro-sensor and wearable technology, cellular-based therapies and growth factors (e.g., mesenchymal stem cells [MSCs], adipose-derived stem cells, and platelet-rich plasma [PRP]).


The SAB's evaluation of the proposals it receives is based on the National Institute of Health's Scoring Guidance, a widely-used system for scoring research proposals (available here). The integrity of the process is entrusted to the expertise of the SAB, who select the projects to recommend to the NFL for funding.


November 15, 2018

In 2018, the SAB reviewed 129 proposals, from which they selected eight finalists to give oral presentations, and provide additional written materials, to the SAB.

After review and evaluation of the science and merit of the finalists' proposals, the SAB recommended five projects to the NFL for funding. The NFL accepted the SAB's recommendations and granted funding to all five projects.


For the purposes of the 2018 funding opportunity, the members of the SAB were selected based on their expertise and background in the field of neuroscience. Each member was identified and selected by Dr. Betsy Nabel, the NFL's former chief health and medical advisor, and Jeff Miller, the NFL's then-Executive Vice President of Health and Safety Initiatives, based on recommendations from and in consultation with members of the NFL's Head, Neck and Spine Committee.

In addition to Gen. Chiarelli, members of the board are:

  • Sidney Hinds, MD, MC, Col. – Brain Health Research Program Coordinator at the Department of Defense;
  • David Hovda, PhD – Director of the UCLA Brain Injury Research Center;
  • David J. Shulkin, MD – former Secretary of Veterans Affairs;
  • Douglas H. Smith, MD – Director of the Center for Brain Injury and Repair, and Robert A. Groff Endowed Professor and Vice Chairman for Research and Education in Neurosurgery at the Perelman School of Medicine, University of Pennsylvania; and
  • Shelly D. Timmons, MD, PhD – Director of Neurotrauma, Vice Chair for the Administration Department of Neurosurgery, and Professor of Neurosurgery at Penn State Health Milton S. Hershey Medical Center.


The SAB's goal was to seek innovative translational research being conducted by investigative teams focusing on the diagnosis and treatment of concussion (mild traumatic brain injury) and associated comorbid conditions, including chronic traumatic encephalopathy (CTE), in addition to the natural history of concussion and associated comorbid conditions.

The awarded funds are intended to help translate original, ongoing and existing research products into clear clinical end points, including diagnostics, drugs, devices and treatments that advantage the patient, as well as advancing understanding of the short-term and long-term effects of concussion and associated comorbid conditions.


The NFL has awarded:

  • $6,070,384 to "Prevalence of Brain Health versus Neurodegeneration in Professional Football Retirees" led by researchers at the University of Pittsburgh and University of Pittsburgh Medical Center (UPMC)
  • $14,698,132 to "A Prospective, LONGitudinal and Translational Study for Former National Football League Players" led by William P. Meehan III, MD at Boston Children's Hospital and Harvard Medical School
  • $9,438,473 to "Surveillance in High Schools to Reduce Concussions in Youth" led by Carolyn Emery, PhD at the University of Calgary
  • $3,454,080 to "Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI Longitudinal)" led by Geoff Manley, MD, PhD at the University of California – San Francisco
  • $1,583,138 to "The Spectrum of Concussion: Predictors of Clinical Recovery, Treatment and Rehabilitation, and Possible Long-Term Effects" led by Grant Iverson, PhD at Spaulding Rehabilitation Hospital and Harvard Medical School

As part of the process established by the SAB, investigative teams will be required to meet an annual timeline of mutually agreed upon research deliverables. The investigators will attend an annual conference to report their findings and progress to representatives of the SAB as it pertains to the milestones outlined in their proposals.

A Prospective, LONGitudinal and Translational Study for Former National Football League Players

Boston Children's Hospital and Harvard Medical School, William P. Meehan III, MD

  • With the goal of determining the neurologic health outcomes associated with concussion and sub-concussive exposure among former NFL players, Boston Children's Hospital has received a 5-year grant of $14.7 million from the NFL to conduct a comprehensive neurologic health assessment and track the progress of former NFL players. In addition, the study will conduct laboratory experiments of 4 potential therapies for the neurological effects of repeated brain trauma. This study is a combined effort with Beth Israel Deaconess Medical Center, the University of North Carolina at Chapel Hill, the Medical College of Wisconsin and University Orthopedic Center – State College, PA. Led by William Meehan, MD, Boston Children's Orthopedics and Sports Medicine Center, the team will conduct annual follow-up neurologic health assessments for as many as 2,500 former NFL players who were originally assessed in 2001. Former players who exhibit impairment will undergo a repeat evaluation three years later. As it nears its conclusion, affected former players will be eligible for a clinical trial of those treatments that appear the most promising in the pre-clinical studies.

Surveillance in High Schools to Reduce Concussions and Consequences of Concussions in Youth–SHRed Concussions

University of Calgary, Carolyn Emery, PhD, Sport Injury Prevention Research Centre, Faculty of Kinesiology and Integrated Concussion Research Program

  • This Pan-Canadian research program will involve a three-year longitudinal study to evaluate concussion diagnostic tools, prognostic indicators, and prevention and management strategies in youth, who account for over half of the annual burden of more than three million concussions in North America. SHRed Concussions seeks to reduce the burden of sport-related concussions (SRC) and their consequences across all youth sport populations in alignment with the NFL goal to facilitate the translation of original research into clear clinical end points that help patients and advance understanding of short and long-term effects of concussion.
  • The SHRed Concussions research team includes >35 researchers representing nine Canadian universities and >30 community, government, and industry partners. The team aims to:
  1. Establish a concussion surveillance program nationally to evaluate concussion burden, risk factors for concussion, and predictors of recovery in 6,000 high school student-athletes across five provinces;
  2. Integrate a variety of tools for SRC to inform the development of multifaceted models to detect concussion and predict recovery;
  3. Evaluate the implementation, effectiveness, and sustainability of novel sport-specific and school-based concussion prevention strategies;
  4. Provide a recruitment platform for treatment studies to prevent long-term consequences of concussion. (Description provided by: University of Calgary)

Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI Longitudinal)

University of California – San Francisco, Geoff Manley, MD, PhD

  • To treat and cure disease, we must understand its natural history and evolution, and the factors that underlie resolution or exacerbation. Advances in cardiovascular disease (CVD) can be credited directly to the Framingham Heart Study, designed to follow the same cohort over years, uncovering risk factors and ways to mitigate and treat those risks, a strategy that has paid global public health dividends. Like CVD, traumatic brain injury (TBI) is a complex pathophysiological process that can have life-long consequences. Unlike CVD, we do not fully understand TBI's natural history.
  • This project leverages the largest precision medicine, short-term natural history study of TBI to date: the Transforming Research and Clinical Knowledge in Traumatic Brain Injury Study (TRACK-TBI), executed by a network of academic, private, and public partners. TRACK-TBI's 3300 injured subjects and controls have been followed for 1 year after their injury; the study has amassed the world's most comprehensive serial collection of TBI neuroimaging (CT and MRI), blood-based and genomic biospecimens, and clinical outcome assessments. In TRACK-TBI Longitudinal, we will seek to further advance our understanding of TBI's natural history by extending follow-up of the TRACK-TBI cohort by an additional 1 year.
  • We will re-contact the entire cohort with one annual telephonic follow-up, capturing neuropsychological and cognitive symptoms and life function/quality, screen for neurodegenerative disease (e.g., dementia, Alzheimer's, CTE, Parkinson's, ALS), and post-traumatic disorders (e.g., post-traumatic epilepsy); a subset of responding participants will undergo in-person assessment, including advanced MRI, provide biospecimens for biologic and genetic analyses; subjects will be invited to consent to brain donation for neuropathologic analyses.

The Spectrum of Concussion: Predictors of Clinical Recovery, Treatment and Rehabilitation, and Possible Long-Term Effects

Spaulding Rehabilitation Hospital and Harvard Medical School, Grant Iverson, PhD

  • Dr. Iverson is leading a multidisciplinary team of experts from the United States, Canada, and Australia to conduct transformative research across the spectrum of concussion in collision sports such as football, hockey, soccer, rugby and more. The team will examine acute effects, functional recovery, treatment and rehabilitation for youth who are slow to recover, possible long-term effects on brain health, and rehabilitation of retired amateur athletes.
  • The team will conduct and publish at least 16 studies. Among the goals of the studies are to understand the effects of concussion in young athletes with pre-existing conditions, examine pre-injury predictors of clinical recovery from concussion, look at risk factors for persistent symptoms in High School and Collegiate Athletes, develop new approaches for youth athletes with persistent symptoms following concussion, and develop a new virtual treatment program for retired athletes with chronic pain and brain health problems.
  • The study pulls from data on more than 60,000 high school student athletes, and post-injury data from more than 5,000 students. In addition, a web-based injury surveillance system includes more than 30 high schools and 11 Division III colleges. including 1,451 individuals who sustained a concussion.
