WR Steve Johnson questionable
Johnson hurt his shoulder in Sunday's loss to Dallas, and didn't practice on Wednesday.
He returned Thursday, and coach Chan Gailey seemed optimistic on Friday that Buffalo will have its top receiver against the Dolphins (2-7).
The Bills (5-4), though, may be without starting strong safety George Wilson, who hurt his neck in the Cowboys game. Wilson, who leads the team with four interceptions, didn't practice all week.
Carpenter hurt his right groin in practice Thursday and was limited in Friday's workout. Fasano, nursing a sore right ankle, also was limited.
Cornerback Nolan Carroll (hamstring) is listed as probable. He's the only other player on Miami's injury report.
