Eagles' running back Brian Westbrook vows to work very hard this week while rehabbing in an attempt to play against the Bears this Sunday night, according to Philadelphia Daily News. Coach Andy Reid said the injury is "literally a day-to-day situation, and I'm sure it'll be a race to get him ready for Sunday." "I'm going to do everything that it takes - if it takes me being [in rehab at NovaCare] from 7 in the morning until 7 at night, that's what I'll do," Westbrook said. "If I can run, then I'm going to be out there," Westbrook added.
