As planned, the Vikings placed Peterson on the active/physically unable to perform list, giving their star halfback further time to recover from the major knee surgery he underwent less than seven months ago.
"We think that's the best thing to do for right now," coach Leslie Frazier said of Peterson, who tore the anterior cruciate and medial collateral ligaments in his left knee on Dec. 24 at Washington and had surgery six days later.
"We'll continue to evaluate him daily, see how he's progressing, and at some point, the doctors and our head trainer Eric Sugarman will come to me and say, 'Hey, we think he's ready to get involved in some team activities.' But at this point, we're going to go through some evaluations, just make a determination as to when is the right time to put him out there with his teammates."
Two NFL sources told 1500ESPN.com on Thursday morning the Vikings planned to make the long-anticipated move. But Frazier said he planned to meet with Peterson about the plan before finalizing anything, and Peterson told reporters he intended to fight the designation.
"He put up a fight. He did," Frazier said. "Knowing Adrian like you guys do, he wanted to make sure -- 'Coach, don't hold me back. Let me get out there.'
"He wants to get out there, but we've got to be smart. We need to see him do a few things and then make a determination. But if he had his way, he'd be getting involved (Friday)." (1500 ESPN)
