Just saw this on Sportsline regarding Westbrook's injury:
"Nobody responds better to adversity than Philadelphia's Andy Reid, and here we go again. With running back Brian Westbrook sidelined with a bruised sternum, Reid may have to turn to Reno Mahe and/or Dorsey Levens for next weekend's game with Baltimore -- provided, of course, that Westbrook's injury is as serious as it seemed Sunday. There is, however, another running back we're forgetting here, and that's quarterback Donovan McNabb. If you saw him run for 28 yards in overtime, you'd understand."
You might want to pick up Levens if you have Westbrook.
