UFC on FX 4 has filled up very quickly over the last few days, and the UFC continued the trend by adding the first featherweight bout to the card. One guy long been touted as a top featherweight prospect, while the other seemingly came out of nowhere to pick up two UFC wins so far. UFC.com shares the news:

Two of the featherweight division's top prospects return to action on June 22nd in Atlantic City, as unbeaten Jimy Hettes, fresh off back to back wins over Alex Caceres and Nam Phan, takes on The Ultimate Fighter 14 vet Steven Siler, who has two consecutive Octagon wins of his own, having beaten Josh Clopton and Cole Miller. This bout has been verbally agreed to.

Hettes was originally going to enter the UFC in late 2010, but contract issues with another promotion delayed his debut by nine months. Once he did make it to the big leagues though, he proved why he was tipped as a solid prospect by submitting Alex Caceres at UFC on Versus 5. He was then given a spot on the UFC 141 PPV main card and made the most of it, thoroughly dominating Nam Phan and winning a wide decision (that included two 30-25 scores).

Siler came onto the scene as a contestant on The Ultimate Fighter 14. He submitted former WEC fighter Micah Miller to get into the house, but was knocked out by Diego Brandao in 30 seconds in his next bout. He made his official UFC debut at the TUF 14 Finale, where he picked up a decision win over Josh Clopton. The UFC then decided to capitalize on a storyline by booking Siler against Micah Miller's brother Cole Miller in his featherweight debut. Siler shocked just about everyone by controlling the fight and picking up a decision win.

The bout should take place on the main card.
