Harvin left the team after a July 31 practice for personal reasons. He had a death in the family and then found out he had a close friend pass away. He was also suffering from migraine headaches.
Last week, the team placed him on the roster-exempt list and presented him with a letter indicating he needed to report back to the team within five days.
Harvin, according to sources, was in the Minneapolis area Sunday night and showed up at the team facility Monday morning.
He was plagued by migraine problems last season but was able to win the rookie of the year honors on offense.
