Vikings RB Peterson leaves with ankle injury

Minnesota Vikings running back Adrian Peterson and New England

Patriots tight end Rob Gronkowski have been sidelined by right leg

injuries.

Peterson and Gronkowski each are expected to undergo an MRI on

Monday.

Peterson, the NFL’s leading rusher, left in the second quarter

of Minnesota’s 29-26 loss at Baltimore after he hurt his right foot

when he was tackled on an icy field. Gronkowski departed New

England’s 27-26 victory over Cleveland in the third with a

suspected torn anterior cruciate ligament in his right knee.

The Vikings also lost tight end John Carlson to a concussion.

Dolphins running back Lamar Miller and Raiders tight end Nick Kasa

and defensive tackle Vance Walker also left their games on Sunday

with concussions.
