Carroll did not expand, but commented a day after he said he was unsure whether Harvin would play again this season.
Harvin had hip surgery in early August to repair his labrum. He returned to practice in late October and made his Seahawks debut in Week 11 against Minnesota. Harvin had one reception and a 58-yard kickoff return in the victory.
But he's been absent since that game, unable to overcome what Carroll has called "soreness" in the hip area. Harvin has not practiced since, but Carroll has said there is no additional structural damage.
