EDEN PRAIRIE, Minn. — Adrian Peterson will have surgery on his right knee to repair a torn meniscus, putting his season and perhaps his 10-year run with Minnesota in question.

The Vikings have held off for now on placing the franchise’s all-time leading rusher on injured reserve, though, waiting for the medical report that will influence that decision. Peterson was hurt on Sunday night during the victory over Green Bay, needing assistance off the field after his knee was slightly twisted while being tackled at the end of a 5-yard run.

Peterson has only 50 yards on 31 attempts this season. He told ESPN on Wednesday morning that the type of tear he was diagnosed with typically requires a minimum recovery time of three to four months. But Vikings coach Mike Zimmer said the timetable for Peterson’s return won’t be clear until after the procedure.
