ORCHARD PARK, N.Y. -- Buffalo Bills running back C.J. Spiller suffered an ankle injury in Sunday's win over the Baltimore Ravens and is uncertain of his status for next Thursday night's game against the Cleveland Browns.
Spiller left in the third quarter Sunday after rushing 21 times for 65 yards. He returned to the game, rushing twice more for 12 yards, but was limping in the locker room following the game.
"I'm going to do as much treatment as I can to get ready for Thursday, but it's a short week, so it's going to be tough," Spiller said. "If I can go out there at least 85 or 90 percent, I'm going to play."
Spiller, who left last week's loss to the New York Jets with a quad injury, said postgame X-rays revealed no structural damage to his ankle. The injury is believed to be just a sprain.
Running back Fred Jackson said he sprained his MCL in Sunday's win but expects to play Thursday night.
"It's not as significant [as last season]. It's something that we can manage, and I expect to play," Jackson said.
Jackson, who rushed for 87 yards on 16 carries Sunday, left late in the third quarter, jogging to the locker room. He returned early in the fourth quarter, rushing five times for 19 more yards.
