## Early career
Miller turned professional in November 2001, winning his debut against Brian Warren by rear-naked choke at Ultimate Pankration 1.[2](https://www.fightmatrix.com/fighter-profile/Jason%20Miller/13768/) • [1](https://www.espn.com/mma/fighter/history/_/id/2354051/jason-miller) He fought frequently in regional promotions in his first years, including a 2002 loss to [Chael Sonnen](https://www.edgepedia.org/chael-sonnen) and a 2003 win over Denis Kang by rear-naked choke at Extreme Challenge 50.[1](https://www.espn.com/mma/fighter/history/_/id/2354051/jason-miller)
His first UFC appearance came on short notice at UFC 52: Couture vs. Liddell 2 on April 16, 2005, where he lost a unanimous decision to [Georges St-Pierre](https://www.edgepedia.org/georges-st-pierre) over three rounds.[1](https://www.espn.com/mma/fighter/history/_/id/2354051/jason-miller) He returned to the Zuffa-owned WEC in May 2007, defeating Hiromitsu Miura by unanimous decision at WEC 27.[7](https://www.mmafighting.com/2011/04/22/172903/jason-mayhem-miller-signs-with-ufc)
## Strikeforce and DREAM
Miller's most prominent run came in Strikeforce and the Japanese DREAM promotion. In 2008 he fought [Ronaldo Souza](https://www.edgepedia.org/ronaldo-souza) at Dream 4, losing a unanimous decision, and beat [Katsuyori Shibata](https://www.edgepedia.org/katsuyori-shibata) by TKO at Dream 3.[1](https://www.espn.com/mma/fighter/history/_/id/2354051/jason-miller) On November 7, 2009 he challenged [Jake Shields](https://www.edgepedia.org/jake-shields) for the Strikeforce middleweight championship at Strikeforce: Fedor vs. Rogers and lost a five-round unanimous decision.[1](https://www.espn.com/mma/fighter/history/_/id/2354051/jason-miller) • [8](https://www.mmafighting.com/2009/11/07/188973/strikeforce-middleweight-title-fight-breakdown-jason-miller-vs)
After that loss he won consecutive fights against Kala Hose by rear-naked choke and Tim Stout by TKO at Strikeforce: Nashville in April 2010.[1](https://www.espn.com/mma/fighter/history/_/id/2354051/jason-miller) The Nashville event also produced the incident that shaped the rest of his career: Miller entered the cage during Jake Shields' post-fight interview and a brawl involving the Diaz brothers followed, and the Tennessee State Athletic Commission fined and suspended Miller and [Nick Diaz](https://www.edgepedia.org/nick-diaz) over the episode.[9](https://www.mmafighting.com/2010/09/02/183765/inside-the-mind-of-mayhem) • [10](https://www.mmafighting.com/2011/05/03/171986/mayhem-miller-i-wasted-a-good-chunk-of-my-career-due-to-str) Miller later said the suspension cost him a good chunk of his career, and he did not compete for Strikeforce again; fights against Nick Diaz and [Tim Kennedy](https://www.edgepedia.org/tim-kennedy) that were discussed never materialized.[10](https://www.mmafighting.com/2011/05/03/171986/mayhem-miller-i-wasted-a-good-chunk-of-my-career-due-to-str) • [7](https://www.mmafighting.com/2011/04/22/172903/jason-mayhem-miller-signs-with-ufc)
His last fight before returning to the UFC was a submission win over [Kazushi Sakuraba](https://www.edgepedia.org/kazushi-sakuraba), one of his own stated idols, at Dream 16 on September 25, 2010, in 2:09 of the first round.[1](https://www.espn.com/mma/fighter/history/_/id/2354051/jason-miller) • [7](https://www.mmafighting.com/2011/04/22/172903/jason-mayhem-miller-signs-with-ufc)
## Return to the UFC
In April 2011, with his Strikeforce contract expired, Miller signed a new multi-fight agreement with the UFC, confirmed by his manager Ryan Parsons.[7](https://www.mmafighting.com/2011/04/22/172903/jason-mayhem-miller-signs-with-ufc) By then he was better known to general audiences as the host of *Bully Beatdown* than as a ranked fighter, and the UFC matched him against [Michael Bisping](https://www.edgepedia.org/michael-bisping) as rival coaches on *The Ultimate Fighter 14*.[4](https://www.ufc.com/news/mayhem-miller-one-bully-left)
The two met at [The Ultimate Fighter](https://www.edgepedia.org/the-ultimate-fighter) 14 Finale on December 3, 2011, where Bisping stopped him by TKO at 3:34 of the third round.[1](https://www.espn.com/mma/fighter/history/_/id/2354051/jason-miller) Miller's final UFC bout came at UFC 146 on May 26, 2012, a unanimous decision loss to CB Dollaway over three rounds.[1](https://www.espn.com/mma/fighter/history/_/id/2354051/jason-miller) • [6](https://www.ufc.com/athlete/jason-miller) Across his three UFC appearances he went 0-3, with the 2005 loss to St-Pierre preceding the Bisping and Dollaway defeats.[1](https://www.espn.com/mma/fighter/history/_/id/2354051/jason-miller)
## Television and public profile
Miller became a professional fighter in 2001 and was known among MMA fans as an entertainer from early on, from dancing during his ring entrances to his post-fight interviews, but hosting MTV's *Bully Beatdown* brought him to an audience beyond the core MMA community.[3](https://www.mmafighting.com/2009/09/02/190819/mayhem-miller-im-an-entertainer-first-i-entertain-the-masses) He described the two jobs as the same activity, saying he viewed fighting and television as opportunities to entertain.[3](https://www.mmafighting.com/2009/09/02/190819/mayhem-miller-im-an-entertainer-first-i-entertain-the-masses) A 2010 profile by Ben Fowlkes of MMA Fighting described him as intellectually curious and noted that he had enrolled at Saddleback Community College in [Mission Viejo, California](https://www.edgepedia.org/mission-viejo-california), saying he wanted to become a better writer in case he wrote his memoirs.[9](https://www.mmafighting.com/2010/09/02/183765/inside-the-mind-of-mayhem)
## Later career and legal troubles
After leaving the UFC in 2012, Miller fought only sporadically. He lost to John McElroy by rear-naked choke in January 2015 and to Matt Larson by TKO in December 2014, with wins over Dennis Reed and Mike Smith in between, before a final professional appearance at Venator FC 3 in Italy on May 21, 2016, where Mattia Schiavolin submitted him with a rear-naked choke in the second round.[1](https://www.espn.com/mma/fighter/history/_/id/2354051/jason-miller) • [11](https://www.mmaindex.com/fighters/jason-miller) ESPN later reported that the former UFC fighter was facing felony charges.[12](https://www.espn.com/mma/fighter/_/id/2354051/jason-miller)
## Fighting style and statistics
Miller's record was built on grappling: 14 of his 23 recorded wins came by submission and only 5 by knockout or technical knockout, against 2 submission losses and 2 knockout losses.[1](https://www.espn.com/mma/fighter/history/_/id/2354051/jason-miller) The UFC's statistical profile of his Octagon tenure shows the limits of his striking there: he landed 210 of 480 significant strikes attempted, a 44 percent accuracy rate, absorbed 2.30 significant strikes per minute while landing 1.83, and completed only 2 of 35 takedown attempts.[6](https://www.ufc.com/athlete/jason-miller) His average UFC fight time was 10:43, reflecting that all three of his UFC bouts went to a stoppage or decision inside three rounds.[6](https://www.ufc.com/athlete/jason-miller)
