The Louisville product did work Sunday, rolling for 177 yards and 2 touchdowns in the Raiders' upset of the Tampa Bay Buccaneers. It was his first full NFL game, as RBs Darren McFadden and Justin Fargas were both out with injuries.
Bush rambled for 77 yards on the Raiders' final drive, setting up a Sebastian Janikowski FG that iced the victory and destroyed the Bucs' playoff hopes. He carried the ball 27 times on the day, a career high.
