Orchard Park, NY (SportsNetwork.com) - Buffalo Bills running back C.J. Spiller is listed as doubtful for Sunday's game against New Orleans as he continues to battle an ankle injury.
Spiller hasn't yet missed a game but has been slowed recently by the ankle issue. He has started four of the team's seven games this season and has run for 362 yards with a touchdown on 90 carries while adding 14 catches for 36 yards.
Last week against Miami, he managed only 11 yards on six carries and had three catches for minus-four yards in the 23-21 victory.
The Bills also listed linebacker Manny Lawson as doubtful because of a hamstring injury. Lawson has 40 tackles in seven games this season.
Buffalo made a pair of roster moves on Friday, releasing cornerback Brandon Burton and signing running back Ronnie Wingo from the practice squad.
