Minnesota Vikings running back Adrian Peterson, coming off a career-best 2,097-yard season, had surgery for a sports hernia on Thursday, Feb. 7, according to the team's official Twitter feed. "Adrian Peterson had a surgical procedure done today by Dr. William Meyers, in Philadelphia, Pennsylvania," according to the @VikingsFootball Twitter feed. "Dr. Meyers was able to successfully repair Adrian's abdominal core muscle injury (sports hernia). We expect a speedy recovery with no long-term concerns." Peterson rushed for the second-highest total in NFL history in 2012, finishing just nine yards short of breaking Eric Dickerson's mark of 2,105 that he set in 1984 with the Los Angeles Rams. Last weekend, Peterson was voted the NFL's Most Valuable Player and the league's Offensive Player of the Year, beating out Denver quarterback Peyton Manning in both races.
