EDEN PRAIRIE, Minn. — The Vikings have placed running back Adrian Peterson on injured reserve, the team announced Friday.

Peterson, 31, suffered a torn meniscus on Sunday, just two games into his 10th pro season.

Jerick McKinnon and Matt Asiata filled the void in 2014 when Peterson missed all but one game, and are expected to do the same moving forward. Zimmer said McKinnon is likely to start against the Panthers on Sunday.

The Vikings also signed veteran free agent Ronnie Hillman on Wednesday.

Peterson underwent **successful surgery** on his right knee on Thursday.

The Vikings have not exercised the one "designated-to-return" option on a player on injured reserve, but Peterson and Matt Kalil would be eligible for that option later this season.

Peterson rushed 31 times for 50 yards in the first two games this season, moving to 16th all-time with 11,725 career rushing yards.
