ARLINGTON, Texas (AP) Pittsburgh cornerback DeMarcus Van Dyke left Sunday's game at Dallas after hurting his right shoulder on a special teams play.

Van Dyke didn't return after getting hurt on the Steelers' first punt less than 2 minutes into the game trying to tackle returner Dwayne Harris.

Dallas starting linebacker Ernie Sims sustained a concussion. The Cowboys said he took a blow to the head on another play in the first quarter, and said after halftime he wouldn't return.

After Harris got away from Van Dyke and was quickly tackled by another Pittsburgh player, Van Dyke remained sitting on the field. He walked off the field with two trainers.

The Steelers initially said Van Dyke was doubtful to return, but a few minutes later said he was out for the game.

Pittsburgh receiver Emmanuel Sanders, who played at nearby SMU, sustained a rib injury before halftime. He was on the sideline in the second half, but hadn't been back in the game.
