Despite hints by Vikings coach Leslie Frazier that running back Adrian Peterson might play in Friday's preseason game against San Diego, NFL.com reported Monday that Peterson will not play in that game. Peterson, who had surgery to repair a torn anterior-cruciate ligament on Dec. 30, came off the physically unable to perform list on Aug. 12 and has had a week of practice. But the team has been adamant about not rushing Peterson back into action. On Sunday, Frazier did not rule out the possibility of Peterson playing on Friday, saying it would depend on how Peterson feels. But team sources have told NFL.com that Peterson will not play.
