ORCHARD PARK- Injuries continue to pile up for Buffalo Bills as they prepare to visit the 9-2 Oakland Raiders on Sunday.

After recording two sacks against the Jacksonville Jaguars in Week 12, Bills defensive lineman Marcell Dareus was limited in practice Wednesday.

Dareus dealt with an abdominal issue late in Sunday's game. Darues has also injured his hamstring and groin this season.

Despite being limited in practice Wednesday, Bills head coach Rex Ryan is confident Dareus will be "ready to roll" in Oakland.

Wide receiver Sammy Watkins was first listed as "limited" but then downgraded to "did not participate" after he told trainers he had soreness in his foot.

Also limited in practice Wednesday: RB Mike Gillislee (hamstring), Richie Incognito, Preston Brown (hand), Sergio Brown, John Miller

Meanwhile, a handful of Bills did not practice at all on Wednesday: WR Robert Woods (knee), WR Percy Harvin (illness), TE Charles Clay (knee), LB Lorenzo Alexander (ankle), CB Ronald Darby (concussion), OT Cordy Glenn (ankle), James Ihedigbo

Quarterback Tyrod Taylor was also added to the injury report with a groin issue but was listed as a full participant. Taylor said the soreness came from Sunday's game against Jacksonville but he'll be ready to go this Sunday at Oakland.
