INJURY REPORT Roy Williams (Cowboys, S): Broke his right forearm for the second time in his first game back from the previous injury, and owner Jerry Jones said he'd miss the remainder of the season. Williams, who has made the past five Pro Bowls, was hurt midway through the third quarter vs. the Rams. Reggie Bush (Saints, RB): Hobbled off the field after a punt return late in the first half vs. the Panthers after aggravating a left knee injury that kept him out of practice some last week. Jonathan Goodwin (Saints, C): Left in the second quarter because of a left knee injury. Keith Rivers (Bengals, LB): Broke his jaw on a jolting block by Steelers WR Hines Ward, likely ending Rivers' season. Bryant McFadden and Troy Polamalu (Steelers, CB and S): Got hurt on the same play in the fourth quarter. McFadden suffered an arm injury and Polamalu lost his helmet while tackling Benson and was unsteady as he walked off the field.
