Minnesota Vikings rookie Percy Harvin returned to practice Friday and the team gives him a 50-50 chance to play in Sunday's game at Carolina. Harvin was absent all of last week and stayed home again Wednesday and Thursday because of severe problems with migraine headaches. Harvin said he felt fine, grateful for the opportunity to work up a sweat for the first time in nearly two weeks. "I should be on the field on Sunday," he said, "but we'll see."
