Vikings' Adrian Peterson helped to locker room with right knee injury

— -- MINNEAPOLIS -- Minnesota Vikings announced running back Adrian Peterson had been ruled out for the rest of the team's game against the Green Bay Packers?with a right knee injury.

Peterson had to be helped to the locker room after injuring his right leg in the third quarter of Sunday's game.

Peterson stayed down on the field after a 5-yard run with 3:32 left in the third quarter, and he hobbled off the field with the assistance of athletic trainers. After being examined on the sideline, he hopped through a field-level club at the team's new stadium toward the Vikings' locker room.

Upon arriving in the locker room, Peterson was quickly ruled out.

The 2015 NFL rushing leader, who had just 19 carries for 31 yards last week against Tennessee, was injured on his longest run of the night.

He'd gained only 19 yards on 12 carries, though his presence had helped Vikings quarterback Sam Bradford hit Stefon Diggs on a pair of long strikes off play action.

Peterson suffered a devastating left knee injury in 2011 -- tearing both his ACL and MCL ligaments -- only to bounce back and rush for 2,007 yards in the 2012 regular season.
