Michael Bush, who has not played in a game since suffering a broken leg in the season-opener of his senior year at Louisville, had been hopeful of working into the Raiders' backfield rotation but never got his chance.
He had been practicing with the team for the past three weeks in anticipation of being activated but now goes back to the PUP list. His status there prevents him from taking part in on-the-field practices but Bush can still attend meetings.
"To work your way back and all of a sudden it's a long time until he gets to play again now … I'm sure he was upset with that but it is what it is," Kiffin said. "I talked to him this morning about today, he's competing to be the starting running back next year, and he should go about every day that way … the way he works in the weight room, the way he pays attention in the meetings and how serious he prepares."
Meanwhile, Dominic Rhodes continues to be perplexed by his own status. Signed away from the Super Bowl champion Indianapolis Colts in the offseason, Rhodes has spent most of his time on special teams while playing sparingly, if at all, on offense.
Heading into Kansas City, Rhodes has carried the ball just 12 times for 24 yards.
"That's the hardest part, knowing that I do have to be patient, and know that I have, over the course of a couple of years, I have put a good product on the field and not really understanding why I can't get a shot here," Rhodes said. "But I'm just being patient and let the process work itself out.
"I probably wouldn't have came here if I wouldn't have been able to play, know what I'm saying? So, I know there are a lot of teams I'd be starting (for) right now. But hey, I think God does things for a reason and I'm just here waiting for opportunities."
