Top UFC lightweight contender T.J. Grant better hope Anthony Pettis doesn’t get his wish. Pettis (16-2 MMA, 3-1 UFC), who dropped from lightweight to featherweight for a shot at 145-pound champion Jose Aldo (22-1 MMA, 4-0 UFC) before a knee injury scrapped their UFC 163 headliner this past week, now wants to return to 155 pounds. And he wants to take a UFC 164 title shot with lightweight champion Benson Henderson that was promised to Grant (21-5 MMA, 8-3 UFC). UFC 164 takes place Aug. 31, four weeks after Pettis’ planned UFC 163 bout with Aldo in Rio de Janeiro
