Minnesota Vikings running back Adrian Peterson leads the NFL in rushing, but Peterson is still bothered by an ankle injury he suffered in Week 5.

Vikings head coach Leslie Frazier said the bye week helped Peterson, but his ankle still bothers him. Frazier said the Vikings may reduce Peterson's workload in practice to help ease the strain on his ankle. While his ankle may be sore, the injury hasn't slowed Peterson's production.

He's rushed for 1,128 yards on the season and is averaging 5.8 yards per attempt. Since suffering the injury against Tennessee, Peterson has rushed for 708 yards in five games. He's been at his best recently, rushing for at least 123 yards in each of Minnesota's last four games.

Frazier said the bye week gave Peterson and chance to rest and reflect on the first 10 weeks of the season. Peterson is less than 11 months removed from the serious knee injury he suffered last season.
