Harvin was release from the hospital and returned to the facility.
Harvin was seen on the field before practice in light workout gear before heading inside to workout with the trainers.
With Harvin missing all but a few practices this year with migranes and Sidney Rice recovering from offseason hip surgery, the Vikings have been looking for WRs on the free agent market.
The team just worked out Javon Walker and has been linked to Brandon Jones as well.
