Though still in the concussion protocol, Bills quarterback Josh Allen was a limited participant in Wednesday's practice.
He participated in non-contact football specific activities, which means that Allen is in step four of the league's return to participation protocol.
There are five steps in the protocol, with the final step being full medical clearance by the Team Physician and an Independent Neurological Consultant. If cleared he'd then be able to practice fully and play in games.
There is however, no timetable on any of the steps in the protocol. Every concussion case is different. This past summer, center Mitch Morse was in step four of the concussion protocol for more than a week before being fully cleared.
Safety Dean Marlowe, who also left Sunday's game with a concussion is in step four of the protocol as well. He was a limited participant Wednesday.
Also limited were Taron Johnson and Devin Singletary who are trying to return to action from hamstring injuries.
Bills OT Ty Nsekhe was sidelined due to an ankle injury Wednesday. No word on the severity of the injury, though he was on the sidelines at practice observing the session.
Joining him was Pat DiMarco, who is also in concussion protocol. He was doing aerobic activity on a stationary bike, so he is in step three of the return to participation protocol.
Tyler Kroft and Corey Thompson are still sidelined by ankle injuries.
