02:06 PM ET 11.30 | Carolina Panthers running back Jonathan Stewart is listed as doubtful for Sunday's game with the Kansas City Chiefs because of ankle injuries. Stewart has not practiced this week and said on Thursday that both his ankles hurt after re-injuring his right ankle it during the first half at Philadelphia. He also sustained a high ankle sprain to his left leg in the second half. If Stewart can't play, DeAngelo Williams would likely start against Kansas City. Williams was removed from the starting role in place of Stewart earlier in the season.
