Alameda, CA (NFL.com) - Oakland Raiders running back Darren McFadden sat out his second consecutive practice with a sore hamstring and almost certainly will miss Sunday's game against the San Diego Chargers.
McFadden's absence would be a blow to Oakland's sputtering offense. The former first-round draft pick is tied for third in the NFL with 392 rushing yards, 35 more than he had all last year. It's the best start by a Raiders running back since Lamont Jordan ran for 424 yards after four games in 2007.
The Raiders insist McFadden's injury isn't like the one that sidelined him early in training camp, but coach Tom Cable said it was "very, very doubtful" that the third-year pro would play Sunday.
Instead, Oakland will lean heavily on Bush, who has just 10 carries this season after leading the team in rushing in 2009.
Bush's power running is in stark contrast to the quicker, slashing style of McFadden, although Cable doesn't believe the Raiders will alter their offense much because of the change.
"If you look at when Mike's played, it's been the same things," Cable said. "He runs more physical in the box, maybe. You may not get as much play on the perimeter, but you'll get it running downhill at the defense. (McFadden) has been very productive, so we've got to find a way to get that same production, but I think Michael's ready to take that load."
Neither Bush nor McFadden were made available to the media Thursday. McFadden didn't attend practice.
