Orchard Park, NY (WGR 550) -- The Buffalo Bills are entering the final two weeks of the 2013 regular season, and an injury may prevent one of their most improved defensive players from suiting up in the team's upcoming game.
Safety Aaron Williams missed his second consecutive practice due to an injury to his ribs, and remains firmly in the questionable category for Buffalo's contest against the Miami Dolphins on Sunday.
Despite another day of practice time missed, head coach Doug Marrone didn't become more pessimistic at the safety's chances to play.
"I think I'm still 50-50," the coach said. "We'll see how it goes."
He originally labeled Williams as "50-50" on Wednesday.
Besides the safety, quarterback EJ Manuel, wide receiver Stevie Johnson and linebacker Arthur Moats did not participate in Thursday's session. Manuel has already been ruled out of Sunday's game with a knee injury, Johnson isn't likely to play due to the death of his mother and Moats was excused from practice for a non-injury related reason. The linebacker is expected to play Sunday, however.
Running back Fred Jackson returned to practice on a limited basis after getting Wednesday to rest an injury to his ribs. Jackson is expected to play against the Dolphins.
Defensive linemen Kyle Williams (Achilles) and Marcell Dareus (ankle), along with cornerback Brandon Smith (ankle), all returned to practice in full on Thursday.
The Bills and Dolphins are scheduled for a 1 pm start on Sunday at Ralph Wilson Stadium.
