For Jones and Gustafsson, who will battle to determine the new UFC light heavyweight champion, this is a rematch numerous years in the making.
"When they told me I wouldn't be getting the title fight, it sucked a little bit but I was ready to go out there and prove myself again", Weidman said.
Sure, he promised his family he'd retire when he turned 40, but people break promises all the time.
The announcement did not go over well with fans, and a couple of weeks later the fight was scrapped when the UFC announced Derrick Lewis would be challenging Daniel Cormier for the heavyweight title in the main event this Saturday in NY.
"I like Brock, I really do". He turns the big 4-0 in March and vowed long ago that would be the age when he retired. "It's just coming to a head now". They first met for the light heavyweight title in January 2015, with Jones winning a unanimous decision.
As it turns out, that didn't matter because Whittaker couldn't fight anyway but the title shot had already been granted to Gastelum.
Seated on one side of the dais were women's bantamweight champion Amanda Nunes and Alexander Gustafsson, with featherweight titleholder Cris Cyborg and the returning Jon Jones taking up residency on the other side of the stage. Cormier took his back and forced him to tap out. But Jones was more popular and Cormier's reign as the light heavyweight champ during Jones' absences wasn't validated until he defeated Miocic.
Separated by UFC President Dana White, the heated rivals who are set to resolve their differences inside the Octagon on Saturday, December 29 at T-Mobile Arena in Las Vegas, Nevada exchanged verbal jabs in the build-up to what should be an explosive night of fights to end the year. It hasn't always been good. "I'll believe you when you're in the cage". The Cormier-Lewis main event will likely start after midnight ET.
"Isn't it unbelievable that it took 10 years (to get the recognition), but it is what it is", Cormier said Thursday from media day for UFC 230, which he is headlining with a heavyweight title defence against Derrick Lewis.
"This is a guy that can finish a fight in one punch", Cormier said. "I'm an optimistic guy".
In general, most fighters don't get to announce when they're going to retire.
"I win the fight, I go, 'Brock, you obviously wanted it. Get your a** in here if you wanted it.' Now, I didn't know he was going to push me. I like breaking dudes".
