The Bills' stretch of amazing comebacks ended when they couldn't stop a rookie quarterback from pulling off one of his own. Andy Dalton shook off a horrid first half and led his first game-winning drive in the NFL on Sunday. Mike Nugent's 43-yard field goal as time ran out gave the Cincinnati Bengals a 23-20 victory over the previously unbeaten Bills in front of the smallest crowd in Paul Brown Stadium's history.
