Vikings RB Peterson taken off PUP list

The Minnesota Vikings running back Adrian Peterson was activated from the physically unable to perform list on Sunday.

Peterson, who had surgery to repair both a torn anterior cruciate ligament and medial collateral ligament in his left knee on December 31, is scheduled to participate in the Sunday afternoon practice. Due to the new collective bargaining agreement, however, Peterson will be unable to take part during padded practices for two days.

"I want to caution you, I know there are a lot of fans that are very optimistic and excited about seeing him back but for us it's just a part of the process," head coach Leslie Frazier said. "It doesn't mean a whole lot other than he's done a great job in his rehab up to this point."

Frazier wants to "see how he (Peterson) progresses," but hasn't ruled out Peterson from playing in a preseason game.

Frazier added that Peterson will be evaluated daily to check his progress.

"If we could get him in a game and let him get a little bit of the taste of NFL action and a live situation, that would be good," Frazier said.

Peterson finished 2011 with 970 rushing yards and 12 touchdowns on 208 carries. It was the first time in his career that he didn't eclipse 1,000 yards rushing.
