Westbrook missed one game this season with an ankle injury, but it's too early to know if his latest injury will keep him out of Sunday's game at San Francisco.

"We just have to see," coach Andy Reid said Monday. "We have to see how it all works out and exactly the pain level there. Right now, he's very sore, so we'll see how things go over the next few days."

Westbrook had 84 total yards against the Redskins. He leads the Eagles (2-3) with 194 yards rushing and has six touchdowns, two receiving.

He said he was taking a wait-and-see approach, but that Correll Buckhalter should take his place in the backfield if the injury is limiting him too much later in the week.

"Do I want to be out there at 45 percent and not wanting to take a hit and hurting this team more than I'm helping it?" Westbrook asked on his radio show on 950 ESPN. "No. ... I wouldn't want to set the team back like that."
