LAS VEGAS – A day after Jon Jones  was announced as the headliner of UFC 170, the light heavyweight champion has been scratched from the card. UFC President Dana White today confirmed the bizarre news, though he declined to elaborate on the reason. In fact, he said he learned of Jones unavailability just before today’s UFC 167 press conference in Las Vegas. However, White said Jones (19-1 MMA, 13-1 UFC) will still fight Glover Teixeira  (22-2 MMA, 5-0 UFC) in his next bout, and it could take place as early as March
