Minnesota Vikings running back Adrian Peterson was hurt when he was tackled near the sideline on an icy field. It was a low hit that shelved New England Patriots tight end Rob Gronkowski.
The result was a pair of right leg injuries for two of the NFL's best players.
Peterson injured his right foot Sunday when he caught a short pass from Matt Cassel, headed to the right sideline and was tackled by Arthur Brown in the second quarter of Minnesota's 29-26 loss at Baltimore.
"I haven't seen the replay, but my foot was extended and kind of got rolled up, kind of like a horse-collar tackle type," said Peterson, who is among the NFL leaders with 1,221 yards rushing. "I just felt it pop a couple times and the pain was excruciating. I came in and tried to tape it up again after getting the X-ray done. I just couldn't do it with the push off."
Peterson is expected to undergo an MRI on Monday. Asked If this could be a season-ending injury, the 2012 NFL MVP said: "Not at all. You should have seen me in here trying to get back out there. I kept my pads on, too, until the third quarter, until I finally was just like, 'I'm not ready to go.'"
It was a much different situation in New England, which lost Gronkowski to a suspected torn anterior cruciate ligament in his right knee during the third quarter of a 27-26 victory over Cleveland.
