UFC 151 Gets Castillo-Johnson, Siver-Yagin, Mizugaki-Hougland

---

A trio of new bouts has been added to the UFC 151 dance card, including a lightweight clash between Danny Castillo and Michael Johnson. Promotion officials also revealed Wednesday that featherweights Dennis Siver and Eddie Yagin will collide at the Sept. 1 event, as will bantamweights Takeya Mizugaki and Jeff Hougland.

Verbal agreements are in place for all three announced contests. UFC 151 is headlined by a light heavyweight title collision between reigning champion Jon Jones and ex- Strikeforce and Pride Fighting Championships titlist Dan Henderson. The event takes place at the Mandalay Bay Events Center in Las Vegas and airs live on pay-per-view.

Castillo, 32, has won six of his last seven and rides a three-fight winning streak heading into his meeting with Johnson. “Last Call” closed out last year with victories over Shamar Bailey and Anthony Njokuani before kicking off 2012 with a unanimous decision win over John Cholish at UFC on Fox 3 last month.

Johnson, 26, arrived in the UFC as a member of “The Ultimate Fighter” Season 12, fighting his way to the show's finals before falling to Jonathan Brookins at the live finale. Three wins in four fights would follow for “The Menace,” who showed off his ever-improving standup skills in his May 5 decision victory over “TUF 13” champion Tony Ferguson.

Known for his stout frame and powerful spinning back kick, Siver saw a four-fight lightweight winning streak halted by Donald Cerrone last October, prompting the Russian-born German to make the cut to 145 pounds. The move proved successful, as Siver outpointed the world-ranked Diego Nunes in his April 14 featherweight debut in Stockholm.

A former Tachi Palace Fights champion, Yagin made his UFC debut with a loss to Junior Assuncao last September. “The Filipino Phenom” rebounded from the defeat in his most recent appearance, however, taking a split decision from former title challenger Mark Hominick in a “Fight of the Night” performance at UFC 145.

Mizugaki, 28, made his North American debut when he challenged Miguel Torres for his WEC bantamweight strap in 2009. The former Cage Force titlist then split his next four bouts in the WEC before joining the UFC, where he has also alternated wins in losses in his four Octagon appearances to date, most recently dropping a split nod to Chris Cariaso on Feb. 26.

Hougland last competed on May 15, stepping in as an injury replacement for Mike Easton against Yves Jabouin at UFC on Fuel TV 3. “Hellbound” was battered for virtually the entirety of the contest but survived to hear the final bell. The loss snapped a nine-fight winning streak for the bantamweight, who earned a win over Donny Walker in his promotional debut nearly one year ago at UFC 132.
