Only one day after Bruce Gradkowski acknowledged that he didn't need surgery on his injured shoulder, the Oakland Raiders officially placed him on injured reserve and signed former San Francisco 49ers quarterback J.T. O'Sullivan. And one week after being replaced, Jason Campbell finds himself the starter again.
Cable initially expressed concern that the quarterback's injury could be season-ending, but an MRI confirmed that Gradkowski has a third-degree shoulder separation, the same injury he sustained earlier in the year. It doesn't require surgery.
"It seems like my shoulder's still strong to where if I just let it heal right, I'll be all right," Gradkowski said Wednesday. "I don't see the season being over for me yet. I'm just going to keep preparing, keep rehabbing. I'm thinking a couple of weeks and get back."
Campbell handled the majority of reps in practice Wednesday, and Kyle Boller was the backup. Gradkowski attended practice and even donned a helmet at one point, but he was held out of all drills.
O'Sullivan, who was drafted by the New Orleans Saints in 2002, also has spent time with the Green Bay Packers, Minnesota Vikings, New England Patriots, Carolina Panthers, Detroit Lions, 49ers, Cincinnati Bengals and San Diego Chargers. He appeared in games for four of those teams -- the Packers, Lions, 49ers and Bengals.
