Later that day, the Browns placed Manziel in the concussion protocol and sent the former first-round pick home. Manziel missed a scheduled medical treatment four days later, and was subsequently fined. Sashi Brown, Browns executive VP of football operations, said on Jan. 21 that the team was unsure of the reason for Manziel's absence, though reports placed Manziel in Las Vegas with friends.
Silver said Friday on NFL Network that the Browns lied when they placed the quarterback in the concussion protocol, an assertion the team refuted in a statement released on Tuesday.
Following the team statement, Silver tweeted he regretted saying the team lied and said he would take the team at their word regarding Manziel's diagnosis.
The Dallas Police Department is currently investigating Manziel after receiving a complaint of domestic violence assault against him. Last week, Manziel's agent Erik Burkhardt, announced he has parted ways with the QB. Manziel's father, Paul, expressed concern that his son's life is in danger.
"I truly believe if they can't get him help, he won't live to see his 24th birthday."
