Adrian Peterson is the latest to say that the New Orleans Saints defense might not be squeaky clean.

Peterson, who played for the first time in a month Sunday because of a high ankle sprain, ripped cornerback Jabari Greer for targeting his ankle, saying that Greer twisted it during a pile-up.

“I came into the game kind of expecting that coming back from a high ankle sprain,” Peterson, who had 10 carries in the Vikings’ 42-20 loss, said (via “Guys are going to try to take their shots when we're on the pile and try to twist it up and things like that.

“I felt like it kind of got overboard. I got up and kind of got in his face. Thank God I was able to keep my composure.”

Greer said he though the issue was behind him and AP.

“I talked to him. I didn’t apologize, but I told him, ‘You know what, man, I was just trying to get you down and it’s the game of football,’ ” Greer said. “ ... I also talked to him after the game. ... I thought we had squashed the beef. Then I find out the beef wasn’t squashed. It was open and it was stanking. I don’t know what to say about that.”

A little over a week ago, the Tennessee Titans accused the Saints of dirty play after strong safety Roman Harper grabbed the facemask of Titans wide receiver Damian Williams. Harper was fined $7,500 for that play and $15,000 for roughing the passer in the same game.

“I'm going to step out in public and say it — he's dirty,” Titans wide receiver Nate Washington said. “That was dirty, what he did. It was unfortunate that he grabbed the facemask. And at the same time, you don't walk over a guy and nudge him with your knee. You don't do that. That's dirty. Honestly, that's a dirty player. This is not just one game. He's been doing it all season. I'm tired of it.”

Gregg Williams, the Saints’ defensive coordinator, is, as he was with the Washington Redskins, a proponent of smashmouth defense.

"If that guy doesn't want his head tore off, duck. Because that's how we're playing,” he said of Harper’s play last week. “He needs to duck, okay? And that is exactly what you have to do. One of the things about playing in this league is that your mental toughness, your physical toughness, all that kind of stuff works hand-in-hand. And I love Roman Harper and the way he plays, and evidently a lot of other people and players in the league do, too, because they keep on voting him to the Pro Bowl.”
