Seahawks coach Pete Carroll acknowledged Thursday that Percy Harvin may need surgery to repair the tear in his hip labrum. Harvin is scheduled for a second opinion next week but early signs appear grim. "When you spoke to people this afternoon about this injury" ESPN's Adam Schefter said on NFL Live "they sounded concerned." The second opinion in all likelihood will confirm Harvin's need for surgery. Carroll is typically pretty vague on injury situations but he was revealing in this case and we don't take that as a good thing. Should Harvin miss regular season time -- and that's now a very real possibility -- the Seahawks' three-receiver set would be Sidney Rice Golden Tate and Doug Baldwin.
