A featherweight bout between Steven Siler (21-10 MMA, 3-1 UFC) and Jimy Hettes (10-1 MMA, 2-1 UFC) is the latest addition to April’s UFC 159 event.

Siler today announced via Twitter that he’s signed a bout agreement for the fight.

UFC 159 takes place April 27 at Prudential Center in Newark, N.J. The main card, including a headliner between light heavyweight champion Jon Jones and Chael Sonnen, airs on pay-per-view following prelims on FX and Facebook.

Siler vs. Hettes, which initially was expected to take place this past June at UFC on FX 4 before Hettes was forced off the card with an injury, likely will be part of the prelims.

Siler, a semifinalist on “The Ultimate Fighter 14,” won his first three UFC fights, including decision wins over Josh Clopton and Cole Miller, as well as a submission victory over Joey Gambino. However, in his most recent bout, he suffered a decision loss to Darren Elkins to UFC 154.

Hettes, meanwhile, opened his career with a 10-0 mark, which included UFC wins over Alex Caceres and Nam Phan (he also won his first nine fights via submission). However, the Pennsylvania-based fighter then suffered a decision loss to Marcus Brimage back in September, which marks his most recent appearance.

The latest UFC 159 card includes:
