UFC 319 is set to take over Chicago this weekend as the United Center plays host to a highly anticipated main event between two undefeated UFC fighters. Middleweight champion Dricus Du Plessis will defend his crown against Khamzat Chimaev in a clash of styles that has fans buzzing.

The middleweight championship is up for grabs at Saturday's UFC 319. Champion Dricus du Plessis will be putting the title on the line against top challenger Khamzat Chimaev in the night's main event.

Chimaev earlier came in under the limit at 183lb, despite bizarrely opting to use the curtain to strip down naked. Brazilian Caio Borralho also weighed in at 184lb as the back-up, but will now not be needed for the title fight.
