Running back Adrian Peterson remained on the turf after a five-yard run in the third quarter. He was carried to the sideline, then the locker room with a right knee injury.

After the game, Vikings coach Mike Zimmer said he couldn't rule out whether or not Peterson's injury was serious, adding the running back would have an MRI on Monday morning.

"He might miss a week, I don't know if he will or not," Zimmer said. "Whatever it was has calmed down now, so we'll see."

Peterson left the locker room on crutches with his right knee in a brace.

Peterson's previous ACL surgery was on his left knee.

Peterson finished with 12 carries for 19 yards.
