Vikings center John Sullivan had surgery last week to repair a microfracture in his left knee, but is expected to be ready for training camp at the end of July, according to a person with knowledge of the situation. Sullivan played all 16 games for the Vikings, being named an alternate to the Pro Bowl, finishing third in the NFL All-Pro voting and keying a Vikings offensive line that helped Adrian Peterson rush for 2,097 yards. He was listed on the team's injury report with a knee injury once, before the Vikings' Nov. 25 game against the Chicago Bears, but needed an operation after the season. He will need three to four months to recover from the injury, which means he will miss the majority of the Vikings' offseason program. But when the Vikings report to camp in Mankato, their center should be healthy.
