"The Buffalo Bills are going to have to prepare for two quarterbacks this week — and the possible return of Dolphins left tackle Jake Long, too.

Matt Moore, who sustained a mild concussion in Sunday's loss to the Eagles, according to Dolphins interim coach Todd Bowles, returned to practice on a limited basis Thursday and sounded optimistic about playing Sunday.

Bowles said Thursday he'll probably wait until Sunday to decide whether or not to dress Moore in uniform against the Bills. But if Moore has any say, he — and not backup J.P. Losman — will be running the Dolphins offense at chilly Ralph Wilson Stadium."
