The Oakland Raiders placed defensive tackle Warren Sapp on injured reserve Saturday with a right shoulder injury, prematurely ending his 11th NFL season. Sapp, who turns 33 next month, had been listed as doubtful during the week for Sunday's home game against the Miami Dolphins after injuring his shoulder during the Raiders' 16-13 win at Washington last Sunday. He has a torn rotator cuff, the team said. Sapp wasn't sure when he got hurt in the game. He had an MRI exam Wednesday and coach Norv Turner didn't immediately know the results, though Oakland downgraded Sapp to out on Friday's injury report. "It's not a separation, no," Turner said Friday. "They're just making sure in terms of the structure and everything inside. I think we'll know something in a few days where he's at."
