"Oakland quarterback Jason Campbell participated in Monday's walk-through practice, showing no ill effects of the stinger and wrist injury sustained in Saturday's exhibition game against the 49ers. He threw the ball and did everything the other quarterbacks did in practice.
"I knew after (Saturday's) game that he would be all right," coach Tom Cable said, "so it was just a matter of him going back to work."
In an odd turn, the Raiders would not verify that running back Michael Bush had the expected surgery on his thumb.
Oakland released four players - tight end Tony Stewart, receiver Paul Hubbard, guard Allen Smith and fullback Chane Moline - and has one more cut to announce today. The final cut from 75 to 53 players is Saturday."
