Eagles' Westbrook leaves with bum ankle; McNabb returns after chest injury

PHILADELPHIA -- Eagles running back Brian Westbrook strained his ankle in Philadelphia's 15-6 win over Pittsburgh on Sunday and will have an MRI on Monday.

Eagles coach Andy Reid said X-rays on the ankle were negative but the team would do more tests.

Westbrook did not speak with reporters but was on crutches in the locker room after the game.

Westbrook appeared to get hurt while hurdling a teammate on a 2-yard run early in the second period. He limped off the field and was attended to on the sideline before walking to the locker room. He did not return.

The Eagles scored on the possession, with backup running back Correll Buckhalter hurdling a defender to get into the end zone after taking a pass from Donovan McNabb.

But McNabb remained in the locker room after halftime with a chest injury, then returned to play in the third quarter. Reid said McNabb bruised his chest when he was landed on earlier in the first half.

"He was stiff a bit," Reid said. "He was in some pain."

Reid said he did not expect the injury to hinder McNabb any further.

"I'm sure he'll be sore, but I think he'll be all right. He's not going to be going out and doing any gardening tomorrow."

McNabb was replaced by second-year backup Kevin Kolb. McNabb returned to the sideline and briefly warmed up before re-entering the game with 9:17 to go in the third.

He completed a 5-yard pass to Buckhalter on his first play back.

McNabb was 16-for-19 for 147 yards with one touchdown and one interception in the first half.

Without Westbrook and with McNabb hurting, the offense sputtered in the second half. McNabb was 8-for-16 for 49 yards after halftime. The offense produced only three second-half points on a field goal set up by a Steelers turnover.
