Tyson Fury vs Oleksandr Usyk undercard, running order and exact UK fight times

Tyson Fury and Oleksandr Usyk are the main attractions - but not the only ones - at tonight's event in Saudi Arabia.

Similarly, this weekend's victor in Riyadh - assuming there is one - will be the undisputed No. 1 and reign supreme as the toughest man on the planet.

However, before the headline act commences, there are several captivating bouts on the undercard, including one featuring the next big British heavyweight star, and two additional world title fights, along with several other matches that could go either way. Here's all you need to know about tonight's fight card, including UK start times...

Tyson Fury vs Oleksandr Usyk - 11.05pm

The two world champions will clash to determine the first undisputed heavyweight world champion since Lewis in 1999 - and the first-ever four-belt ruler of boxing's premier division. Fury and Usyk have been on a collision course since the latter dethroned Anthony Joshua in 2021 before defeating the Brit for a second time the following year.

Fury first claimed the world champion title in 2015 when he outpointed Wladimir Klitschko in Germany, but never defended his titles due to a battle with drink and drug addiction. He reclaimed his championship status by defeating Deontay Wilder in 2020 and has since defended his belt three times against Wilder in their trilogy bout, Dillian Whyte and Derek Chisora.

Joe Cordina vs Anthony Cacace - 10pm.

Tonight, Joe Cordina will make his second defence of his super-featherweight world title against Northern Ireland's Anthony Cacace in an all-British clash. Cordina initially won his world title in 2022 but was controversially stripped of it due to an injury that prevented him from defending his belt.

In his absence, Shavkatdzhon Rakhimov claimed the title but was defeated by Cordina upon his return. Edward Vazquez was also beaten on points, and Cordina is confident of overcoming Cacace, who has lost one of his 23 professional fights.

Jai Opetaia vs Mairis Briedis - 9pm.

Jai Opetaia aims to prove why he's the new face of the cruiserweight division by decisively ending his rivalry with Mairis Briedis. The pair previously fought two years ago in Australia, with Opetaia narrowly securing a points win.

Briedis hasn't fought since but believes he can reverse the outcome in Saudi Arabia tonight. Opetaia, who is predicted to move up to heavyweight in the future, has knocked out his last two opponents impressively, and another such result will see him reclaim his world title.

Agit Kabayel vs Frank Sanchez - 8pm.

This is a fascinating heavyweight bout that sees two undefeated fighters risk their perfect records in the desert. Kabayel caused a major upset in Saudi Arabia last year when he defeated a worn-out Arslanbek Makhmudov.

Both men have won all of their 24 professional fights, with Sanchez also having experience fighting in Riyadh, where he beat Junior Fa.

Sergey Kovalev vs Robin Sirwan Safar - 7.15pm.

Sergey Kovalev will step into the ring for the first time in two years as the former light-heavyweight world champion competes at cruiserweight for the second time against the unbeaten Robin Sirwan Safar. Kovalev was formidable during his reign as champion, defeating Welshman Nathan Cleverly to secure his belt - but it remains to be seen how he performs now.

Moses Itauma vs Ilja Mezencev - 6.30pm.

British heavyweight prodigy Moses Itauma aims to extend his KO streak as he seeks to make significant progress in the division. Already touted as the successor to Tyson Fury, Itauma fights for the ninth time as a professional and has already claimed six of his victories by first-round KO.

He will have Ben Davison, former trainer of Fury and current coach of Joshua, in his corner for the first time.

Mark Chamberlain vs Joshua Oluwaseun Wahab - 5.45pm.

Chamberlain is set to fight in Saudi Arabia for the second time in as many months, aiming to maintain his unbeaten record. He previously defeated Gavin Gwynne in the fourth round of their March bout and will now face Joshua Oluwaseun Wahab, who has only been beaten once, in a 12-round match for a minor WBC belt that could elevate the winner's ranking.

David Nyika vs Michael Seitz - 5pm.

The first fight of the afternoon will see either David Nyika or Michael Seitz lose their undefeated status as they go head-to-head in Saudi.

Isaac Lowe vs Hasibullah Ahmadi - 4pm.

Tyson Fury's stablemate, Isaac Lowe, will aim for his fourth consecutive win as he makes his debut in Saudi. His opponent, Afghan Hasibullah Ahmadi, has only one loss but his record is less than impressive, suggesting there may be early celebrations for the Fury camp.

Daniel Lapin vs Octavio Pudivitr - 3.15pm.

Daniel Lapin, a teammate of Usyk's who often fights on his undercards, will risk his unbeaten record against the once-defeated Octavio Pudivitr in one of the evening's early bouts.
