The Minnesota Vikings aren’t concerned about running back Adrian Peterson’s sprained left ankle.

Players were given Monday off, but Peterson was at the team facility for treatment. The NFL’s rushing leader was seen walking in the locker room without a limp or support, the day after he was hurt in a victory over Chicago.

Peterson carried the ball six times in the second half after his foot rolled underneath the weight of a Bears defender and finished with 63 yards on 18 attempts.

Coach Mike Zimmer said “he’ll be fine,” citing head athletic trainer Eric Sugarman’s assessment: “He’s like Rubber Man.”

The Vikings host the New York Giants on Sunday night.
