Tackle Mark Dixon hasn't been ruled out yet, but it's highly doubtful he'll play. He hasn't taken part in a full practice yet, so it's difficult to envision him being able to play.
The prognosis is better when it comes to safety Shawn Wooden, who sustained hamstring and hand injuries against Houston.
