Daniel Cormier will finally get his rematch with Jon Jones -- the UFC announced it's happening at UFC 214 in July.
It's one of the most heated rivalries in pro sports -- these guys hate each other with a fiery passion.
Cormier says Jon is a drug abusing, lying, cheating bad person. Jon once invited Daniel to perform oral sex on him.
Jon emerged victorious the first time they fought back in January 2015. Cormier has vowed to avenge the loss ever since.
