Two of the greatest fighters in UFC history make their Octagon returns after long layoffs when Jon Jones defends the heavyweight championship against two-time former champion Stipe Miocic in the main event of UFC 309.

Former UFC title challengers Chael Sonnen and Anthony Smith, as well as retired lightweight contender Paul Felder will serve as a desk analysts on the UFC 309 post-fight show and throughout the card, when necessary. Brendan Fitzgerald will serve as the host.

Tom Aspinall is over trying to force a fight with Jon Jones. The British heavyweight champion has had a meteoric rise in the UFC, securing the interim belt at UFC 295 instead of Jones-Miocic and defending it at UFC 304 in July 2024.
