Vikings running back Dalvin Cook left Sunday's 39-10 win over the Bolts with a shoulder injury and was ruled out for the remainder of the contest.
Cook took a handoff early in the third quarter to the left side and was tackled by Denzel Perryman and injured on the play. Making his way to the medical tent, Cook emerged, but didn't have his helmet on and was ruled out by the team with the Vikings leading 18-10. Mattison was inactive in Week 15 and so it was Boone who rushed for 56 yards and two scores. It will be an interesting Viking RB situation heading into Week 16.
