Vikings running back Adrian Peterson is recovering from groin surgery, his third offseason operation in as many years, but the Vikings aren’t worried his availability for the first minicamp of the offseason in April.

Coach Mike Zimmer said Friday that Peterson is “doing great” in his rehab from the operation and that he should be “great to go” for Zimmer’s first minicamp as the team’s head coach. Zimmer also said that he isn’t particularly concerned with the effects of wear and tear on Peterson after 2,033 carries over his first seven NFL seasons.

“This guy isn’t an average 28- or 29-year-old back,” Zimmer said, via FOX Sports North. “This guy is special and some of the things, when we were fixing to play him, some of the things that I thought, I watched him and I was like, ‘Wow, if we’re not really good in the way we line up and contain and be in the right positions, we’re going to have a hard, hard day.’ He could have been 20 months old for all I care.”
