Harvin (head) plans to retire, ESPN's Jeremy Fowler reports.
Harvin came out of retirement to play for the Bills last season, only to be sidelined after two games by the migraines that have bothered him throughout his career. A first-round selection back in 2009, the speedy 28-year-old is apparently calling it quits for good. He isn't fielding offers in free agency -- which may or may not have been the case at this time last year.
