Buccaneers' coach Jon Gruden admitted on Monday that running back Earnest Graham could be lost for the rest of the season because of a right ankle injury. Graham was hurt on his only carry in Sunday's 19-13 win over the Vikings. "His status for the rest of the season is very much in question right now," Gruden said Monday. "I don't have the exact medical terms, but I will say right now, it doesn't look like he'll play anytime soon."
