Minnesota Vikings running back Adrian Peterson is scheduled to visit Philadelphia-based specialist Dr. William Meyers next week to evaluate his troublesome groin and decide if surgery is needed, a person with knowledge of the situation told USA TODAY Sports on Saturday. The person spoke on condition of anonymity because they weren't authorized to discuss the situation publicly. eterson, 28, missed two of the Vikings' last three games because of the groin as well as a foot injury and dropped out of the Pro Bowl last week. Meyers performed Peterson's sports hernia surgery after last season. One possibility for relieving groin pain is an adductor release, which is minimally invasive, cuts an irritated tendon and would require about two months of rehabilitation. The groin was an issue since at least mid-November, most notably hobbling Peterson in a Nov. 17 loss at Seattle. He finished the season with 1,266 rushing yards in 14 games, one year after winning the MVP and rushing for 2,097.
