Munguia–Zon is announced on the card, but its advertised WBA title status requires confirmation. The WBA has separately ordered Munguia to negotiate with mandatory challenger Bektemir Melikuziev. That order does not establish Melikuziev as a replacement opponent on this show. WBA mandatory order.
The championship picture
Advertised title fights on the undercard
Jaime Munguia vs Nikita Zon
The organiser advertises this super-middleweight matchup as a WBA title defence. However, the WBA’s September order set a negotiation period with Melikuziev through 21 October. A newer primary-source approval for the Zon defence has not been verified for this guide, so the advertised belt status remains qualified. WBA announcement.
Rafael Espinoza vs Lorenzo Parra
The announced contest is a defence of Espinoza’s WBO featherweight championship at 126lb. It adds a lower-weight world-title bout to a show headlined at super-middleweight. Check the final programme for when it appears in the broadcast. Promoter’s title-fight details.
Lindolfo Delgado vs Arthur Biyarslanov
Delgado and Biyarslanov are announced for the vacant IBF junior-welterweight championship at 140lb. The advertised prize is a vacant belt; neither boxer is presented here as its defending champion. The Ring announcement.
Beyond the title contests
The rest of the supporting card
Six more pairings complete the announced undercard in the table above. They include Picasso–Martin and Tsutsumi–Garcia, alongside the other listed supporting contests. The longer names are included to distinguish the fighters when checking programme or betting listings.
Being named on the event card does not establish an individual start time, scheduled round count or position in the UK broadcast. Those details are left unconfirmed rather than inferred from a fighter’s usual weight class or the order of a promotional list.
Before choosing which bouts to watch, check the final card for opponent changes and the broadcaster’s coverage of preliminary contests. An event announcement and a UK programme listing answer different questions.
