ENGLEWOOD, CO - Denver Broncos quarterback Kyle Orton is listed as questionable for Sunday's game against the Oakland Raiders.
Orton was limited in practice all week by bruised ribs suffered in last week's loss to the Arizona Cardinals.
The sixth-year signal-caller out of Purdue has completed 293-of-498 passes for 3,653 yards, 20 touchdowns and nine interceptions during the first 13 games of the season.
Safeties David Bruton (ribs) and Darcel McBath (quad) are also listed as questionable for Sunday's divisional contest.
Meanwhile, veteran safety Brian Dawkins will miss his third straight game with a knee injury. Wide receiver Demaryius Thomas (ankle) and kicker Matt Prater (groin) have also been ruled out for the game.
