Mike Florio of Pro Football Talk writes that Bruce Gradkowski will likely start for the Raiders on Sunday against the Dolphins. Gradkowski took most of the first-team snaps in practice this week, according to a source.

Trevor Scott, who is tied for the lead in sacks for the Raiders, was placed on injured reserve on Wednesday. Scott tore his ACL while covering a punt in Sunday's loss at Pittsburgh. "I think it's huge," Raiders coach Tom Cable said. "We've been fortunate to not lose too many guys like this. He does do a lot for our football team, playing in base defense as well as third down and [on] a number of special teams. It's a big loss but we're going to have to rally."

The Raiders have signed former Denver first-round pick Jarvis Moss. The linebacker was waived last week.

Raiders defensive tackle Richard Seymour has been fined $25,000 for punching Steelers quarterback Ben Roethlisberger on Sunday. Seymour was ejected in the second quarter after the offense.

The Raiders benched Jason Campbell on Sunday against the Steelers, but coach Tom Cable says he'll remain the team's starting quarterback. "Yeah," said Bruce Gradkowski, who replaced Campbell against Pittsburgh. "I mean, that's not my decision. So I mean I can't do nothing about it."

Lane Kiffin's two-year-old grievance seeking unpaid salary he felt he was owed after being fired by the Raiders has been denied by an NFL arbitrator, according to a source. Oakland's countergrievance for lawyer and arbitration fees was also denied, the source said. Kiffin had been seeking about $2.6 million when the grievance was initially filed.

The Raiders have turned a corner and Tom Cable was asked on Thursday how the players have suddenly bought into his philosophy. "Well, obviously, results," said Cable. "Results are always the exclamation point. But the real truth of it is, is you've got to be more stubborn as a coach than the problem, if that makes sense. We've never ducked trying to change the attitude, trying to change the environment in the locker room and that sort of thing. We've never dodged that. We've dealt with it. We've talked about it. We've learned to communicate, learned to trust each other. You have to do those things. You have to work at those things. They just don't happen. Knowing what the problem is, you have to be willing to stand up to the problem. If you're bigger than the problem, then you can make it happen. If you're not, the problem wins. So, I feel like, as a coaching staff and as a football team, together, that we've become bigger than what our negatives are, and that's why we're succeeding."

Raiders owner Al Davis likes Jason Campbell and has expressed his desire to have Campbell be Oakland's starting quarterback to coach Tom Cable, reports The San Jose Mercury News. "Mr. Davis likes what Jason has done the past month and doesn't see the need to change when things are going well," a person familiar with the situation told the newspaper. "He thinks Jason is a classic fit for the Raiders style of play." Campbell has led Oakland to three-straight victories. He opened the season as the starter after being acquired in a draft-day trade from Washington. He was benched in favor of Bruce Gradkowski at halftime of the home opener against St. Louis in Week 2. Gradkowski rallied the Raiders to a win over the Rams and started the next three games before being sidelined by a separated shoulder against San Diego.

Raiders coach Tom Cable has changed his mind and will continue starting Jason Campbell at quarterback. Cable had previously said that Bruce Gradkowski would immediately start again once his right shoulder sprain is healed. "I really haven't wavered, but I do have a belief in me about when you're dealing it and you got the hot hand, and things are going in the right direction for your football team, why would you make a change?" Cable said. Campbell has guided Oakland to three consecutive wins, while throwing just one interception.

The Raiders have secured their first sellout in years, but they will likely be without two of their best players on Sunday against the Chiefs. Oakland cornerback Nnamdi Asomugha and tight end Zach Miller are dealing with injuries that are expected to keep them off the field. Asomugha has a sprained ankle and Miller a sore arch. Raiders head coach Tom Cable said both players will try to "work out Sunday morning and (he'll) make a decision at that point."
