The Bills official site reports that the team could be without OT Ed Wang about 4 to 8 weeks after thumb surgery:
Bills head coach Chan Gailey gave a ballpark prognosis on how long offensive tackle Ed Wang might be out following left thumb surgery. “It depends on how quickly things heal,” said Gailey. “I would say the best we’re talking about is four (weeks) and the worst we’re talking about is eight (weeks), but don’t hold me to either one of those.” Gailey confirmed that surgery by all accounts was a success. “Everything went well,” he said.
