The fourth overall pick in 2008,Al Horford Jersey, McFadden was unable to practice Wednesday and his status for Sunday is uncertain.
"It's more than what we initially had thought so he wasn't able to go today,Air Max 97 Scontate," Raiders coach Dennis Allen said. "Hopefully we'll be able to get him out there soon but I don't know."
The oft-injured McFadden has already missed four games this season with hamstring injuries. He came back to play against Dallas on Thanksgiving,Wholesale China Jerseys, but carried just five times for 13 yards and apparently injured his ankle at some point during the 31-24 loss.
