Luke Rockhold and Lyoto Machida, two middleweight contenders, are currently slated to fight at UFC on FOX 15 in Newark, N.J. on April 18, according to sources with knowledge of the situation.

Rockhold (13-2) has won his last three fights in a row, most recently submitting Michael Bisping in November. Meanwhile, Machida (22-5) is coming off a first-round TKO win over C.B. Dollaway last month.

Both fighters, as well as UFC president Dana White, have expressed interest in the fight recently. Rockhold told MMAFighting.com last week that he was hopeful the fight would get made soon.

UFC on FOX 15 will take place at the Prudential Center in New Jersey. The UFC has yet to officially announce the matchup.

Update: Rockhold said he will face Machida next on Instagram, and the UFC has since confirmed that the fight will serve as the five-round main event of UFC on FOX 15.
