"That groin is bothering him," coach Leslie Frazier said. "It definitely affected him. There were a couple of moments when he was so close to breaking it and just couldn't get that one key ingredient to get it going. He's not 100 percent."

"Actually, it was bothering me a lot," Peterson said of the injury. "There were a couple plays in the first half, oh man, I knew if I was able to explode the way I normally do I could have gotten some big chunks, even taken it to the house."

Meanwhile, the Seahawks, like all teams, know Peterson is the Vikings' main offensive threat. So they built their game plan around stopping him. They often had eight men waiting for Peterson at the line of scrimmage during obvious running situations.

There's some question as to whether he might be better off sitting out until the injury heals. Otherwise, he faces a risk of making it worse. Peterson said he didn't think that was necessary. He previously had been hobbled by a bad hamstring.
