Eagles running back Brian Westbrook missed another practice on Friday. He suffered a concussion in Philadelphia's win over Washington on Monday night. "It's going to be a game-day decision," coach Andy Reid said of Westbrook. "We're waiting to get more tests back and see how they look. So far the tests we have done this week have looked OK. But it comes down to a matter of time." The Eagles are set to face the Giants in Philadelphia this Sunday.
