The UFC celebrates the July 4th long weekend by going home to the T-Mobile Arena in Las Vegas, NV for UFC 239! In the main event, Jon Jones squares off against Thiago Santos in a defense of his UFC Light Heavyweight Championship. Below that, Amanda Nunes will defend her bantamweight title against Holly Holm. Still below that, there are a lot fighters on the card who need a little help standing out. With the Reebok policy in place, one of the few ways left to do that is with entrance music.
