The NFL’s top-rated passer shrugged off the flu and played most of Sunday with a strained left calf, leading Green Bay to a 20-3 victory at the Tampa Bay Buccaneers — clinching at least a wild-card playoff berth. Joique Bell scored the go-ahead touchdown on a sweet run in the fourth quarter, Ndamukong Suh had two sacks and Calvin Johnson added six catches for 103 yards for visiting Detroit, which locked up its second trip to the postseason in 15 years when Philadelphia lost to Washington on Saturday.
