Harvin was attending the NFL rookie symposium in Palm Beach Gardens, Florida with all of the other 255 draft picks, when he told the medical staff he wasn't feeling well and was excused by the event organizers.
The report coming from the league's website NFL.com, which reported the story.
This isn't the first time Percy Harvin has been sent home due to being sick.
In April, Harvin was flying to Minnesota to participate in the Vikings' initial rookie mini-camps when he started feeling ill on the plane.
Harvin actually threw up on the plane coming from Florida to Atlanta, and was sent to a nearby hospital, where he was hostipalized with a virus and severe dehydration.
Percy Harvin was however, released a few days later, only to miss the mini-camps.
