Vikings running back Dalvin Cook was carted off the field late in the third quarter after sustaining a shoulder injury and was ruled out for the remainder of Minnesota's Week 12 game at San Francisco.
Coach Mike Zimmer did not have an update on Cook's condition following the Vikings' 34-26 loss to the 49ers but said the running back would undergo an MRI on Monday.
Cook was injured after receiving a handoff and being brought down by Niners defensive tackle Kevin Givens. The running back lost the ball in the process of being tackled and immediately grabbed for his chest with his right arm when he hit the ground.
