The Vikings' lead back has suffered from chronic dislocations and torn labrums in each shoulder – most recently last November – and therefore is mostly protected from new damage.

The 27-year-old has rushed 43 times for 203 and one touchdown and caught seven passes for 37 yards, and had a season-high 96 rushing yards before leaving last weekend.
The Saints have allowed 418 yards, the seventh-most in the NFL this season, but have only allowed seven receptions for 32 yards to opposing running backs.
