The Philadelphia Daily News reports the Eagles are unsure when RB Brian Westbrook will return from his concussion, and his status for Week 10 at San Diego is questionable. Westbrook, who was hurt in Week 8 at Washington, missed the Week 9 game Sunday against Dallas. He was expected to play after going through practice Wednesday and Thursday before taking Friday off due to a headache. "He felt good during the week," Reid said Sunday night. "He practiced during the week. It's a crazy deal . . . I know this: If he has [headaches], I'm going to go more on the conservative side and take every precautionary measure possible. I'm not going to stick him out there, even if the tests are positive." As for Westbrook's prognosis for San Diego, Reid was noncommital: "We'll just see how he does this next week."
