Roethlisberger (shoulder) doesn't return for second half

LANDOVER, Md. -- Pittsburgh Steelers starting quarterback Ben Roethlisberger didn't return for the second half of Monday's game against the Washington Redskins with a shoulder injury.

Roethlisberger went into the tunnel a little before halftime to have an examination on his shoulder. After Pittsburgh's 23-6 win, coach Mike Tomlin said that the quarterback would be evaluated on Tuesday. He downplayed the injury, however.

"I have no update on Ben at this point," he said. "I'll have more information for you guys tomorrow. Potentially he was capable of going back into the game.but we went down the field with [Byron] Leftwich in there to start the second half. We'll just see how he is."

Roethlisberger jogged out from the locker room onto the sideline as Pittsburgh was lining up to run its second play of the third quarter.

Roethlisberger was standing on the sidelines as Leftwich replaced him in the lineup for Pittsburgh.

Leftwich led the Steelers to a touchdown on his first drive, which included a 50-yard completion to Nate Washington. The score put Pittsburgh ahead 16-6 early in the third quarter.

Roethlisberger held his right arm tight against his body while exchanging congratulations with teammates after that touchdown.

Steelers tight end Heath Miller began the second half on the sideline with an ankle injury.
