Middleweight contenders Lyoto Machida and Luke Rockhold will meet this April at UFC on FOX 15, the promotion announced Thursday.

Set for April 18 from the Prudential Center in Newark, New Jersey, the main card will air on FOX.

Machida (22-5) is a former UFC light heavyweight champion and one-time middleweight contender. He rebounded from a loss to champion Chris Weidman in December, knocking out C.B. Dollaway in his native country of Brazil.

Rockhold (13-2) previously held the Strikeforce title. His lone Octagon defeat came to Vitor Belfort, but he rebounded in 2014 with wins over Michael Bisping, Tim Boetsch and Costas Philippou.
