Percy Harvin returned to action on Sunday night, but the Vikings rookie receiver apparently is dealing with more than severe migraines.
Harvin played against the Carolina Panthers despite missing most of the past two weeks because of debilitating migraines.
Harvin also told NBC's Andrea Kremer that he has two bulging disks in his neck and is scheduled to visit the Mayo Clinic with a team doctor Tuesday. Harvin said the injury was diagnosed during an MRI last week.
