UFC superstar declined Dana White's UFC 300 main-event fight request

A UFC superstar declined Dana White's main-event fight request as the blockbuster card is still without a headliner.

The April 13 card in Las Vegas, Nevada, boasts a number of massive fights, including two fight bouts.

The women's UFC strawweight champion Zhang Weili takes on fellow Chinese fighter Yan Xiaonan while BMF title holder Justin Gaethje meets Max Holloway.

A pivotal lightweight clash between Charles Oliveira and Arman Tsarukyan is also set for the event, not to mention Jiri Prochazka vs. Aleksandar Rakic and Holly Holm vs. Kayla Harrison, among others.

But White has yet to announce the main-event for UFC 300 with the huge card just a couple of months away.

Conor McGregor was briefly linked with a headline slot until the UFC CEO provided a shock timeframe for his return.

In search of a main-event, White and Co. asked Jon Jones, but he turned down the chance to fight at UFC 300.

The UFC heavyweight champion said he wouldn't have been ready in time to defend his title.

Asked if he had received a phone call from the promotion to headline UFC 300, Jones replied: "I did. I got a call from Hunter Campbell, one of the head lawyers of the UFC, asking me... 'Jon, I know it's only nine weeks away, but if there's any chance you're feeling up to it, man, It'd be awesome news for the community that you're coming back and headlining one of the biggest events ever'."

Jones added: "As honoured as I am for the opportunity, I just don't think I'll be ready. I just don't. And so, I'm getting up there in age. I only have a few more events left, and I want to give those events my all and make sure that I come back 100 per cent."

The American, who hasn't fought since beating Ciryl Gane for the vacant UFC heavyweight championship back in March 2023, was supposed to face Stipe Miocic at UFC 295 last November until he was forced to withdraw after sustaining an injury.

Tom Aspinall beat Sergei Pavlovich at UFC 295 to claim the interim UFC heavyweight and was relentlessly called out 'Bones' but to no avail.
