Chris Billam-Smith is set to defend his WBO cruiserweight title against Gilberto Ramirez, the WBA titleholder, in a highly anticipated bout in Riyadh, Saudi Arabia on November 16, 2023. This match is significant for Billam-Smith, who is coming off a victory against Richard Riakporhe, as it serves as a unification fight in the cruiserweight division. Meanwhile, the UFC 309 card at Madison Square Garden features heavyweight champion Jon Jones defending his title against Stipe Miocic, with Tom Aspinall as a backup. The co-main event will see a rematch between Charles Oliveira and Michael Chandler. Additionally, the UFC event includes the return of Bo Nickal and a potentially career-defining bout for Chris Weidman against Eryk Anders. However, the card is not fully complete, as Mauricio Ruffy's opponent for the top prelim fight is yet to be finalized.
