Vikings running back Dalvin Cook was carted off the field on Sunday when playing against the 49ers and was ruled out with a shoulder injury by the team.
Cook was carrying the ball but was tackled in the backfield and fumbled on a hard hit. San Francisco would go on to recover the ball, but Cook stayed on the ground grabbing his left shoulder.
On the tackle, Cook was awkwardly bent and teammates immediately knew it was something concerning. Vikings players removed their helmets and took a knee as Cook was being attended to before being carted off the field.
