NASHVILLE, Tenn. -- The Buffalo Bills announced Saturday morning that quarterback Josh Allen has cleared concussion protocol and is expected play Sunday against the Tennessee Titans.
Allen suffered a concussion after a hit to the helmet during the Bills' Week 4 loss to the New England Patriots. He participated in non-contract football drills throughout the week before turning in a full practice Friday.
Buffalo released offensive lineman Conor McDermott on Thursday, prompting speculation that the team would add a quarterback to its 53-man roster before Sunday's game.
