Josh Allen and Dean Marlowe both in concussion protocol.

Fantasy Impact:
The good news is Allen ran from the field to the locker room, trying to pump the crowd on the way. But, the Bills are at Tennessee in Week 5 then have a bye in Week 6. Off to a 3-1 start, it's possible the Bills hold out Allen until after the bye week when they take on Miami. Barkley would get the start if Allen isn't cleared by this week.
