Vikings running back Adrian Peterson is questionable to return due to an ankle injury suffered in the second quarter.

Peterson injured his ankle when he was tackled on a third down catch with 11:27 left in the first half. He was helped off the field and eventually carted into the locker room. Peterson had X-rays according to the broadcast and walked on his own power inside the tunnel.

Peterson had seven carries for 13 yards in the snowy conditions. Toby Gerhart replaced Peterson at running back on the next series.

Update: Peterson has been officially ruled out. The broadcast said Peterson has left the stadium to a nearby hospital for an MRI.

It'll be the Gerhart show in the backfield in the second half.
