EDEN PRAIRIE, Minn. -- Though he is still waiting for the results of a CT scan on his sprained right foot, Adrian Peterson appears to have avoided a serious injury.
The Minnesota Vikings running back said on Monday that an MRI revealed no ligament damage and ruled out the possibility of a Lisfranc injury, which would have kept Peterson out six to eight weeks and ended his season.
X-rays also showed no broken bones in his foot, and while a CT scan will show the injury in more detail, Peterson said "we're just going through the protocol," and added he expects to play Sunday against the Philadelphia Eagles.
Coach Leslie Frazier was more cautious in his optimism than Peterson was, saying the Vikings sent the MRI results to a foot specialist and adding the tests didn't rule out all possible major injuries.
Peterson's foot was in a walking boot on Monday, and while the running back was planning to play, Frazier wasn't ready to rule out the possibility of sitting Peterson for the final three games of the season -- especially now that the Vikings have been eliminated from the playoffs.
"You can't ignore that fact," Frazier said. "You want to know exactly how severe the injury is, and it helps you make that kind of a decision. So as we learn more about the severity of it, or the lack of severity, then you can make a clear decision about this ballgame and future ballgames in this season."
Peterson also made headlines Sunday by calling out Ravens fans for throwing snowballs and game officials for some of the penalties called against the Vikings.
On Monday, he tweeted about the response he has gotten from fans after his comments.
So if you lose respect for me based of me voicing my opinion! That's totally fine! I still have respect for you!— Adrian Peterson (@AdrianPeterson) December 9, 2013
Frazier and several of Frazier's teammates commented Monday on the behavior of fans in Baltimore.
"It was not specific to anyone. [It was] anyone wearing purple. It's not what the league wants, not what anybody wants," the coach said.
"It's something we'll talk about. I didn't talk about it after the game. But I did see snowballs coming," he said. "Didn't address it right after the game; there were so many things on my mind, obviously, at that time. But it's definitely something we'll have to talk with our security about and make our league aware of as well."
Frazier also said he got a call from the NFL on Monday regarding the officiating in Sunday's game.
"I actually got a call from the league, unsolicited this morning. And it was a good conversation. When we got off the phone, I said if I were asked the question you just asked, I would reference any comments to the league office.
"But the fact that they called should give you an indication of how they felt about things on that day. [The call was] without any provocation from me, so that was encouraging that they wanted to talk about that game from yesterday."
Frazier said it was the second time the league has called him to talk about officiating this season, though he said "I won't be too specific" about when the first call occurred.
