Adrian Peterson underwent surgery Wednesday to repair a sports hernia.
It's the same procedure, performed by the same doctor, that Greg Jennings underwent in the middle of the season. There are no real long-term concerns, but it does add to the legend that was Peterson's 2012 season. He first appeared on the injury report with an abdomen issue ahead of Week 15 and still ran for 596 yards over the Vikings' final four games (including playoffs). He also played in the Pro Bowl. Expect Peterson to be ready for most of the offseason program and his status as fantasy's clear No. 1 overall pick in 2013 drafts is unchanged.
