After two surgeries on his back last fall, center John Sullivan is back at work without limitations, at least in the offseason conditioning part of the program.
Sullivan was at the Minnesota Vikings’ training facility on Tuesday, where he has spent much of his winter and spring getting ready for team workouts that began last week.
Sullivan suffered a herniated disc in his back last training camp, pushed himself to get back by about the midpoint of the regular season and suffered another setback before having a second surgery that ended his 2015 season for good without a single snaps being taken during the season.
