Peterson injured the knee in the third quarter of Sunday night’s win over the Green Bay Packers.
While Peterson is likely out for a few months, the Vikings have the option to bring back one of their players on injured reserve after eight weeks.
Peterson and DT Sharrif Floyd had their right knee surgeries on Thursday, with Floyd’s being arthroscopic surgery, and left tackle Matt Kalil had surgery on Friday morning to repair a torn labrum in his right hip.
Floyd’s procedure was performed by Dr. James Andrews at the Andrews Institute in Pensacola, Fla. Kalil and Peterson had their surgeries performed by team physician Chris Larson at Twin Cities Orthopedics.
Peterson and Kalil were placed on injured reserve, meaning either one of them – but not both – are eligible to come back late in the season.
