MINNEAPOLIS -- After making it through the Minnesota Vikings' OTAs and minicamp "unscathed," center John Sullivan said Thursday he's confident his back will hold up through training camp as he tries to return from two surgeries last season.
Sullivan underwent a lumbar microdiscectomy just before the start of the regular season and needed a second operation after suffering a setback in October. He missed all of the 2015 season -- Joe Berger did a solid job in his absence -- and he'll try to reclaim the starting job once training camp begins next week.
