Jon Jones vs. Thiago Santos, Amanda Nunes vs. Holly Holm Fights Headline UFC 239

The UFC 239 main event will feature Jon Jones defending his light heavyweight title versus Thiago Santos, and Amanda Nunes will put her bantamweight belt on the line against Holly Holm in the co-main event. 

UFC president Dana White revealed the news Wednesday to Brett Okamoto of ESPN.com, who reported that all sides have verbally agreed to the bouts but have not signed any official paperwork.

UFC 239 is set to take place Saturday, July 6, at T-Mobile Arena in Las Vegas.

Jones, who is 24-1 with one no-contest, beat Alexander Gustafsson for the light heavyweight belt at UFC 232 in December 2018. He successfully defended it on March 2 versus Anthony Smith via unanimous decision.

The 21-6 Thiago Santos has won seven of his last nine fights via knockout. He's currently ranked third on UFC's light heavyweight fighter list and beat Jan Blachowicz via third-round TKO on Feb. 23.

Nunes, a dual champion who also holds the featherweight belt, has won eight straight fights. She most recently earned a first-round knockout of ex-featherweight champ Cris Cyborg at UFC 232.

Holm won the bantamweight title in a shocking upset win over previously undefeated Ronda Rousey at UFC 193 in November 2015. A decorated boxer who ranks 13th on BoxRec's all-time pound-for-pound list, Holm sports a 12-4 record and most recently beat Megan Anderson via unanimous decision at UFC 225.
