Vikings | John Sullivan undergoes surgery

Minnesota Vikings C John Sullivan (knee) underwent microfracture surgery on his left knee last week. Sullivan will likely need three-to-four months of rehabilitation, which means he will miss most of the Vikings offseason program. Sullivan is expected to make a full recovery for the start of training camp.
