Andrew Booth Jr. made his first start of the season in a 40-3 loss to the Cowboys on Nov. 20.
The rookie cornerback emerged from the game with knee soreness, and missed Thursday's victory over New England. On Monday, Booth had surgery to repair a meniscus, a procedure that could end his season.
Booth will "more than likely" be placed on injured reserve this week, Vikings coach Kevin O'Connell said, which means he's out a minimum four games. As of late Monday afternoon, O'Connell said he didn't know whether Booth's surgery was a full repair, which would end his season, or a trim that could allow him to return in January.
