http://www.philly.com/philly/sports/20071120_Thumb_at_issue_now_for_McNabb.html Donovan McNabb's problems are twofold. His right ankle is sprained and his right thumb is swollen. Although Andy Reid said yesterday that neither the ankle nor the thumb was broken, one, if not both, of the injuries could keep McNabb from playing against the New England Patriots on Sunday. And here is the kicker: We might not know about McNabb's availability until game time. Kickoff at Gillette Stadium is scheduled for 8:15 p.m. Reid listed McNabb as "day-to-day" with both injuries, and said it was possible that McNabb could practice Wednesday, when the team reconvenes and begins preparing to face the undefeated juggernaut that is New England. It also is possible that backup A.J. Feeley could take every snap in practice, and yield to McNabb on Sunday. And it's possible that Feeley will make his first start of the season against the best team in football, one that is obliterating opponents by an average of 25.4 points per game. We will just have to wait and see. "I'm as worried about the thumb as I am about the ankle, maybe a little bit more because that's what he's gripping the football with," Reid said about McNabb's injuries. "Both of them are day-to-day situations. . . . I've been around him long enough to know when he's ready to go and when he's not. So, I'll get a feel as time goes on here and see how he does."
