Vikes' Peterson has groin surgery
The Minnesota Vikings said their star running back had an operation yesterday to repair his adductor muscle, which is part of the groin. The team said Peterson was expected to be fully recovered in about 6 weeks, giving him plenty of time to heal before offseason workouts get going.
The procedure was performed by Dr. William Meyers at the Vincera Institute in Philadelphia.
Peterson rushed for 1,266 yards in 14 games, missing two in December due to a sprained right foot. The groin problem was lingering long before that, though, sapping him of some of his explosiveness. He acknowledged after a loss at Seattle Nov. 17 that the injury was bothering him "a lot." Peterson gained only 65 yards on 21 carries that afternoon.
This was Peterson's third, though least invasive, surgery in the last 25 months. He had anterior cruciate and medial collateral ligament reconstruction in his left knee in December 2011. Then, after rushing for 2,097 yards and winning the NFL MVP award, Peterson had a procedure done in February 2013 to repair a sports hernia in his abdomen. Meyers performed that surgery, too.
