#Bills WR Isaiah McKenzie concussion.

Got hit on left side of head running over the middle. Initially required training staff assessment, but was able jog off to locker room for further evaluation.

Will have to pass through 5 stage concussion protocol before he can play again. pic.twitter.com/0MTgGm9f4r
