The NFL is conducting an ongoing review of HGH allegations made by Al Jazeera America involving Broncos quarterback Peyton Manning.
The league told the following to NFL Media Insider Ian Rapoport on Wednesday: "The review is ongoing and comprehensive. It involves obtaining and reviewing numerous records, conducting multiple interviews and working with other entities. We do not comment on the specifics of these matters until the review is completed. We are working with MLB and USADA.
After the report was released in December, Manning affirmed that he never used HGH or any banned substances to aid in his recovery from multiple neck surgeries.
Manning's name was unearthed by an Al Jazeera America report that suggested the legendary quarterback had HGH sent to his wife, Ashley, for his personal use. Manning's agent, Tom Condon, did not deny that Ashley received the supplements, and Manning confirmed he was a patient at the Guyer Institute, where Charlie Sly, an intern pharmacist who was cited in the Al Jazeera report, worked. Sly later recanted his claims.
An Al Jazeera reporter who worked on the documentary also said Manning was never directly connected to the use of human growth hormone in its hidden-camera investigation. Manning said that he was only went to the Guyer Institute to use the Hyperbaric chamber and to receive blood flow treatment.
"Between being angry, furious, disgusted is how I really feel, sickened," Manning said following the release of the report. "I'm not sure I understand how someone can make something up about somebody. ... And yet somehow it's published in a story.
"I don't understand that. Maybe you can explain that to me. So it's completely fabricated, complete trash, garbage -- there's more adjectives I'd like to be able to use. It really makes me sick. It makes me sick that it brings (my wife) Ashley into it, her medical history, her medical privacy being violated. That makes me sick. I don't understand that."
