Eagles' running back Brian Westbrook suffered a right ankle strain early in the team's win over the Steelers on Sunday, according to Philadelphia Inquirer. "Westbrook has an ankle strain. and he'll have an MRI in the morning," Coach Andy Reid said. "Off the X-rays, it's not fractured, but we'll do the MRI tomorrow and see what the deal is." Correll Buckhalter took over for Westbrook, scoring the only touchdown of the game on a 20-yard pass from Donovan McNabb. "Any time you have your star guy go down, it's tough," McNabb said. "But I thought Buck [Correll Buckhalter] and Book [Lorenzo Booker] did a good job of filling in. Everybody across the league knows we deal with Westbrook as our first or second option."
