"Running back Darren McFadden hasn't given up hope of returning this season from a right midfoot sprain, though time is running out.

Coach Hue Jackson on Thursday said "it doesn't look great" for McFadden playing against the Kansas City Chiefs on Saturday. Therefore, it's likely that McFadden will miss his eighth straight game.

The Raiders final regular-season game is against the San Diego Chargers on Jan. 1.

An ESPN report Thursday, citing an unnamed league source, said McFadden met with Dr. Robert Anderson last week and underwent numerous tests in an attempt to gauge whether he can play again this season.

Dr. Anderson reportedly told McFadden that his foot is not healed all the way, and McFadden's biggest issue is managing the pain if he wants to play.

Even if McFadden decides to play in the final game, it's doubtful Jackson would sign off on the move unless the Raiders still are in playoff contention. They face the prospect of being eliminated Saturday.

McFadden jogged and worked on lateral movements with a team trainer Tuesday, well away from the rest of his teammates. He wasn't spotted at all the next two days."
