On Saturday UFC heads to FOX for the second time this year with a stacked card headlined by a title eliminator bout in the middleweight division. Top contenders Luke Rockhold  (13-2 MMA, 3-1 UFC) and Lyoto Machida  (22-5 MMA, 14-5 UFC) collide in the UFC on FOX 15 headliner at Prudential Center in Newark, N.J., with a shot at the winner of next month’s UFC 187 bout between champ Chris Weidman and Vitor Belfort potentially on the line. Along with the main event, FOX’s 15th UFC showcase features several bouts of significance. Nine fighters on the card put winning streaks of at least three fights on the line.
