Stephan Bonnar

On September 14, 2019, Bonnar faced Moose in a losing effort at Impact Wrestling's Victory Road 2019.

On October 28, 2018, Bonnar was arrested in Nevada and charged with DUI. At approximately 1:15 p.m., the Nevada highway patrol received multiple reports that there was a red Cadillac, a vehicle owned and being driven by Bonnar, observed driving recklessly and making unsafe lane changes. When the NHP arrived on scene, they witnessed Bonnar had both hands tied and strung up to each side of his inside car handles. The pedestrians on scene said he attempted to flee the scene of the accident, so they were forced to "hog tie" him to the inside of his wrecked vehicle. This entire exchange was recorded via the responding officers body can and aired on the television shows season 4 of PD Cam. Officers also claimed that they could smell alcohol on Bonnar's breath and inside of Bonnar's vehicle. Bonnar was arrested on scene, refused to comply or respond to officers commands, and had to be carried and laid inside the back of the patrol car. He was then taken to the Clark County detention center where he was charged with DUI and resisting arrest.

On August 1, 2017, House of Glory, a New York City independent wrestling company announced that Bonnar would be stepping into a wrestling ring for the first time ever to face another former UFC fighter and independent wrestler, Matthew Riddle. However Riddle backed out and he faced Sho Tanaka from NJPW instead. On December 2, 2017, "Speedball" Mike Bailey defeated Bonnar at IWS Season's Beatings in Montreal.

On August 27, 2014, Bellator MMA announced they had signed Bonnar to a multi-fight deal. Bonnar faced Tito Ortiz on November 15, 2014 at Bellator 131 and lost via split decision.

Shortly after the announcement of Forrest Griffin's retirement, Dana White announced that Bonnar and Griffin would be inducted into the UFC Hall of Fame. Bonnar and Griffin were officially inducted on July 6, 2013.

With the UFC needing to replace the main event at UFC 153, they turned to Bonnar and Anderson Silva to fill the spot left empty by injuries. The two UFC vets squared off in a Light Heavyweight match October 13, 2012 in Rio de Janeiro, Brazil. Silva won the fight via TKO. Bonnar tested positive for anabolic steroids after the fight (Drostanolone).

After his loss to Silva it was announced on October 30, 2012 by UFC president Dana White that Bonnar has retired from MMA competition.

Bonnar was expected to face Karlos Vemola on August 14, 2011 at UFC on Versus 5. However, Bonnar was forced to withdraw from the bout due to an injury and was replaced by Ronny Markes.

Bonnar faced Kyle Kingsbury on November 19, 2011 at UFC 139. Bonnar defeated Kingsbury by unanimous decision (30–27, 30–25, and 30–27).

Bonnar mentioned on the MMA Live Post Fight Show for UFC 101 that he was considering a drop down to Middleweight after two disappointing losses at Light Heavyweight. Despite this, Bonnar next faced Krzysztof Soszynski on February 21, 2010 at UFC 110. Soszynski was victorious at 1:04 in the third round, due to TKO (Cut). Video replays that showed that the cut was opened up by a clash of heads led Bonnar to appeal referee John Sharp's decision. It was announced on March 10 that he had lost the appeal and the result would stand as a TKO win for Soszynski.

Bonnar fought Igor Pokrajac on December 4, 2010 at The Ultimate Fighter 12 Finale. He won the bout via unanimous decision (29–26, 29–26, and 29–26).

Bonnar is a fan of the rock band The Who and used their song "Eminence Front" as his entrance music to his UFC fights. Outside of competition, Bonnar has done commentary work for televised MMA programming, notably serving as the WEC's color commentator for most of 2010, calling 5 of their final 7 cards. He has also made appearances as an analyst on the ESPN2 series MMA Live and for UFC broadcasts on the Fox television networks.

Stephan and his longtime girlfriend were married on October 30, 2009 in Tuscany, Italy. The couple have one son, Griffin Brandon, named after the Griffin-Bonnar fight and in memory of Andrea's late brother, Brandon Brown.

After his loss to Griffin, Bonnar became the staple of the regular UFC Ultimate Fight Night shows at the Hard Rock Hotel and Casino in Las Vegas, defeating such notables as Sam Hoger, James Irvin and Keith Jardine before succumbing to Rashad Evans by way of majority decision. In 2006 Bonnar lost a unanimous decision against Forrest Griffin in the long-anticipated rematch at UFC 62. After UFC 62, Bonnar tested positive for the banned substance Boldenone, a type of anabolic steroid. The commission issued a nine-month suspension on Bonnar's fighter's license and fined him $5,000.
