Steelers quarterback Ben Roethlisberger injured his right shoulder and was replaced by Byron Leftwich to start the second half of Pittsburgh’s game against the Washington Redskins on Monday night.

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

He scored a touchdown on a 1-yard sneak late in the second quarter to make it 10-6.

Houston Texans quarterback Matt Schaub injured his left knee Sunday and was replaced by backup Sage Rosenfels in the second half against Minnesota.

Schaub went 11-of-16 for 139 yards, one interception and one lost fumble in the first half. He was seen limping briefly in the first half after taking a hit from Jared Allen. The Texans said Schaub’s return was questionable.

Philadelphia Eagles cornerback Asante Samuel left Saturday morning’s practice with a strained hamstring.

Samuel was hurt while working in seven-on-seven drills during the team’s first practice in full pads this summer.

“We’ll just see how he does here,” coach Andy Reid said. “I won’t know anything for a bit here.”

The All Pro signed a six-year, $57 million contract with the Eagles after spending his first five seasons with New England.
