Minnesota Vikings center Pat Elflein has a left ankle injury that will require offseason surgery.

Coach Mike Zimmer confirms that Elflein will need a procedure done on the ankle he injured in the team’s loss at Philadelphia in the NFC championship game. Elflein was wearing a walking boot after the game.

The rookie from Ohio State, drafted in the third round, produced a solid debut to help the Vikings make significant improvements on the offensive line in 2017.
