ALLEN PARK -- The Detroit Lions will be down two of their top three running backs when the team hosts the Buffalo Bills this Sunday. Joique Bell (concussion) and Theo Riddick (hamstring) have been officially ruled out for Sunday's contest, paving the way for rookie George Winn to see extended playing time in his professional debut.

Starter Reggie Bush is expected to shoulder the majority of the load, certainly seeing more than the 10 carries he's averaged through the first four games. But offensive coordinator Joe Lombardi said Winn, who was signed off the practice squad earlier in the week, would handle some of Bell's responsibilities because of their similar running styles.

The Lions will also be without tight end Joseph Fauria (anke) and linebacker Travis Lewis (quad) against the Bills. Cornerback Cassius Vaughn (ankle) is doubtful.

All-Pro wide receiver Calvin Johnson (ankle) is listed as questionable and is expected to play. Running mate Golden Tate is probable after suffering a mild hamstring injury during Thursday's practice.

The Lions are also expected to get back right tackle LaAdrian Waddle. He's probable with a calf injury after missing the past three games.

Defensive tackle Nick Fairley (knee), defensive end Devin Taylor (knee) and safety Don Carey (hamstring) are also probable.

The biggest news out of Buffalo's camp is All-Pro defensive tackle Kyle Williams is doubtful after missing the entire week of practice with a knee injury.
