The Pittsburgh Steelers, already missing Pro Bowl safety Troy Polamalu (knee), also lost guard Chris Kemoeatu, a Kahuku alum, to a right knee injury yesterday.

Kemoeatu was injured in the third quarter against the Kansas City Chiefs and did not return to the game.

Meanwhile, St. Louis quarterback Marc Bulger said he took a blow to the head on the team's final possession, apparently on a sack by Arizona Cardinals defensive end Darnell Dockett, and will undergo evaluation today.

Bulger said his head had cleared after yesterday's game.

• Lions rookie Matthew Stafford hurt his left shoulder on what would have been the last play against Cleveland.

Stafford was hit after his throw to the end zone was ruled pass interference and replaced by Daunte Culpepper. He came back to throw his fifth touchdown pass from 1 yard to Brandon Pettigrew for the 38-37 win.

Coach Jim Schwartz said X-rays showed Stafford's collarbone wasn't broken, but added more tests are needed.

• Before and after every snap, the Cowboys' Tony Romo felt the throbbing in his back, the result of an accidental blow while making a first-quarter tackle against Washington.

After Marion Barber's fumble, Washington's DeAngelo Hall recovered and Romo brought him down. As Hall was falling, his knee conked Romo in the back. Romo was so bad after that it was obvious something was bothering him.

• Redskins running back Ladell Betts damaged the MCL in his left knee midway through the first quarter. Coach Jim Zorn said Betts will have an MRI to determine the severity of the injury.

• Redskins right guard Chad Rinehart fractured his right leg early in the third period.

• Buffalo Bills running back Marshawn Lynch (shoulder), guard Eric Wood (broken left leg), guard Seth McKinney (knee) and defensive tackle John McCargo (calf) left the game against Jacksonville and did not return.
