The Star Tribune in Minneapolis reported Harvin was in street clothes when he showed up at practice at the NFL team's practice facility in Eden Prairie, Minn. He was greeted with handshakes and hugs from teammates and coaches, the newspaper said.
Harvin, who was taken to the hospital by ambulance Thursday, has a history of migraines so severe they have prevented him from playing.
The second-year player caught 60 passes for 790 yards and six touchdowns in his rookie season.
