(AP) - Seattle Seahawks wide receiver Percy Harvin has cleared league-mandated concussion protocol and has returned to practice as a full participant. Harvin was on the field for Seattle's practice on Wednesday, his first since suffering a concussion in the second quarter of the NFC divisional playoff game against New Orleans on Jan. 11. Harvin was not cleared last week and was unable to play in the NFC championship game against San Francisco. Harvin's had an injury filled season, playing in just two of 18 games. He had hip surgery in early August and made his debut in Week 11 against Minnesota. Harvin suffered complications after that one game and was unable to make it back until the postseason. He had three receptions and one carry for 9 yards before being injured against the Saints.
