Vikings vs. Bears: Adrian Peterson still battling sore ankle

Even after a week off to rest, Vikings running back Adrian Peterson is still dealing with a sore left ankle going into Minnesota's contest with the Chicago Bears:

"It still bothers him a little bit," said (Minnesota head coach Leslie) Frazier. "I could see a little bit (Monday) in our practice. Still a little sore in some areas, but not to the point where it keeps him from achieving what he has to get achieved. It's still there."

Peterson suffered the injury during Minnesota's Week 5 win over the Tennessee Titans, and he is just 11 months removed from tearing the ACL and MCL in his left knee. Frazier will continue to give the sixth-year veteran out of Oklahoma a lighter workload in practice until his ankle is 100 percent.

Despite the nagging injury, Peterson leads the NFL with 1,128 rushing yards this season, and his 112.8 yards per game easily tops the league. In the five games since suffering the injury, Peterson has rushed for 123 yards or more four times and compiled five touchdowns.

The Bears and Vikings kick off from Soldier Field in Chicago Sunday at noon CT. The game will be televised by FOX.
