At this time last year, the Vikings were uncertain about whether or not running back Adrian Peterson would be ready for the start of the regular season because of surgery to repair a torn ACL.

Peterson wound up answering the bell in Week One and ran off to one of the best seasons by a runner in the history of the league. Peterson had surgery again this offseason, but the repair of a sports hernia left no such questions about his availability.

Peterson was able to participate in every drill during Wednesday’s OTA practice and called the rehab from this year’s surgery a “cakewalk” compared to last year’s knee injury. He said he’s spent extra time building up his abdominal muscles this offseason and felt good carrying the ball during the workout.

“I’m pretty much 100 percent,” Peterson said, via Tom Pelissero of 1500ESPN.com. “Me knowing my body, I would like to be a little stronger in some areas. But I’m feeling great.”

Wide receiver Greg Jennings wasn’t in quite as good condition Wednesday. Jennings sat out the team’s session with an ankle injury that coach Leslie Frazier said was “nothing serious.” Given the price they paid to add Jennings to the team and his problems with lingering injuries last season, it’s no surprise that the Vikings would take things as easily as possible with a player vital to their offensive plans in 2013.
