Girma Berkessa says in the complaint that an "extremely intoxicated" Oher pushed him to the ground, kicked him and called him a homophobic slur several times April 14.
"The most important thing is his health", Panthers coach Ron Rivera said, according to the team's website.
The #Panthers have released veteran OL Michael Oher with a failed physical designation. Oher had been in the NFL's concussion protocol since September and finished the 2016 season on injured reserve. "Michael understood and we expressed that to him", Rivera continued.
Guarding the blind side of star quarterback Cam Newton as the starting left tackle, Oher produced perhaps his finest campaign, allowing a career-low four sacks with only three penalties while on the field for 98.4 percent of plays.
Oher's eight-season, 110-game National Football League career began with Baltimore in 2009. Oher started all 16 regular season games in his first season with Carolina, including three postseason starts.
It was the second move made by interim general manager Marty Hurney since being hired Wednesday. He was a member of the Baltimore's Super Bowl XLVII championship team following the 2012 season.
