ALAMEDA, Calif. -- Darren McFadden is injured again.

After five carries for 13 yards in the Oakland Raiders' 31-24 loss to the Dallas Cowboys on Thanksgiving Day, the Raiders running back missed practice Wednesday with an ankle injury. This after he missed the previous three games with a strained right hamstring.

"He actually injured the ankle in the game the other day and it was [hurt] more than what we had initially thought," Raiders coach Dennis Allen said. "He wasn't able to go today and hopefully we'll be able to get him out there soon, but I don't know."

The oft-injured McFadden has never played more than 13 games in his star-crossed six-year career and has already missed four this season and, having missed Wednesday's practice, is likely to miss Sunday's game at the New York Jets.
