Undefeated prospect Aljamain Sterling is ready to return to the Octagon.

Sterling takes on veteran Manny Gamburyan at UFC on FOX: Machida vs. Rockhold on April 18 in Newark, N.J., UFC officials confirmed with MMAFighting.com. Newsday was the first to report the story.

Sterling (10-0) was supposed to face Mitch Gagnon in October before pulling out with an injury. The Serra-Longo product was then put on the UFC's Australia card in November only for opponent Frankie Saenz and replacement Michael Imperato both to fall out.

In his last bout, Sterling, 25, finished Hugo Viana by third-round TKO in July. He has won both of his UFC fights and is considered one of the top prospects in the bantamweight division.

"Manny is a stud, and he had his turn at bat," Sterling told MMAFighting.com "Now I'm up at the plate, ready to knock the ball out the park."

Gamburyan (14-8, 1 NC) debuted in the UFC all the way back in 2007 and also spent time in WEC after that. The Armenia native dropped down to bantamweight for his last fight, a second-round submission win over Cody Gibson in September. Gamburyan, 33, is 3-1-1 in his last five fights.

UFC on FOX 15 is headlined by a middleweight contender bout between Lyoto Machida and Luke Rockhold. The main card will air live on FOX from Prudential Center.
