Adrian Peterson spent part of his offseason on an operating table for the third consecutive year.
Peterson, the Minnesota Vikings running back who famously recovered from major knee surgery to win the NFL MVP award in 2012, underwent groin surgery Thursday, the team announced in a statement.
Minnesota said Peterson's surgery was done by Dr. William Meyers at the Vincera Institute in Philadelphia. The team said the surgery successfully "repaired Adrian's adductor muscle while also doing a compartmental release."
Peterson, 28, is expected to make a full recovery in approximately six weeks, according to the statement.
Peterson, who had sports hernia surgery last offseason, was bothered much of the second half of the season by a lingering groin injury, as well as a sprained right foot. Meyers performed the sports hernia surgery for Peterson last year.
Peterson injured the groin in a loss at Seattle on Nov. 17 and sprained his foot at Baltimore on Dec. 8 and ended up missing two of the season's final three games. Peterson still finished with 1,266 rushing yards, ranking fifth in the NFL.
He was named to the Pro Bowl for the sixth time in his seven NFL seasons but pulled out because of injury.
