Sam Bradford had a strong Minnesota debut, completing 22 of 30 passes for 286 yards, two touchdowns and no turnovers to lead the Vikings to a 17-14 victory over the Green Bay Packers on Sunday night. The Vikings needed that production and resiliency from their new quarterback on a night they again struggled to get star running back Adrian Peterson going before he was carried to the locker room in the third quarter with a right knee injury. After the game Vikings coach Mike Zimmer didn’t offer many specifics on Peterson’s injury, but said Peterson will get an MRI on Monday morning.
