Rex Ryan: 'Probably a reach' for Karlos Williams to play vs. Titans

It doesn't sound like the Buffalo Bills will have Karlos Williams on the field in Week 5.

Head coach Rex Ryan told reporters after practice Thursday that it's "probably a reach" for Williams to suit up against the Tennessee Titans.

Williams missed practice Thursday and remains in the NFL's concussion protocol.

If Williams can't play Sunday, Boobie Dixon is expected to take on a featured role in the Bills' backfield.
