While the Vikings have held up early against the New England Patriots, they might have just lost one of the few players that they can ill afford to lose.

On a second down play midway through the first quarter, Peterson caught a slant pass from Brett Favre and turned upfield. As he tried to cut back to the middle, it appeared that he got his ankle caught in the Gillette Stadium turf and appeared to turn it.

Harvin was helped off the field by the trainers, and was moving very slowly in doing so.

We’ll keep you updated on his condition as updates become available.
