Tale of the tape
Here is how Tyson Fury and Oleksandr Usyk stacked up before Friday's weigh-ins.
The Fight of the Century is just moments away.
Tyson Fury vs Oleksandr Usyk for all the heavyweight marbles.
History will be made as the first undisputed king of the heavyweights in the four-belt era will be crowned.
I've got goosebumps just thinking about the pair FINALLY trading heavy leather.
Not long until we get to see the pair try to outfox one another.
SunSport's Wally Downes Jr, who is perched ringside, spotted an unusual shirt choice from referee Howard Foster.
Usually, a ref wears a white shirt and any blood turns it a bright and flamboyant pink.
But Howard Foster is in a blue number and the claret has mixed to create a purple-to-brown hue.
He looks like he's just really enjoyed a good plate of BBQ ribs - not officiated a bloody world title fight.
AJ and Ronaldo didn't even watch much of that round 11 action between Opetaia and Briedis, they were nattering away like a pair of grannies in the Co-Op.
"Oh you should have heard what Carl Froch said about you."
"Ohh that Ten Hag was so mean to you..."
Briedis is going for broke and swinging for the fences.
And who can blame him given the success he had in the 11th round.
This is the most trouble we've seen Opetaia in. He needs to establish the distance and pump out the jab to keep the Latvian at range.
A HUGE right hand from Briedis stiffens the legs of Opetaia. But Opetaia recovers.
Briedis is sensing a big, big upset in the final seconds of the fight. But he fails to land the Hail Mary he needs to level their series.
What a fight.
Briedis landed a good right hand towards the end of the tenth and is coming on strong after the restart.
The momentum has shifted and the Lativan is putting Opetaia on the backfoot.
And he's trying to turn this contest into a dogfight. Opetaia would be wise to get on his bike and box at range in the final round.
The packed Kingdom Arena is silent but it's out of respect and intrigue instead of ambivalence.
The crowd claps at the end of every exciting round. But they are spellbound during the action and have no bar to race to during every break.
There are the occasional loud shouts for a favourite, the Irish went nuts for Cacace.
But the travelling Traveller army will light the place up when they bundle in soon.
AJ is sat next to Ronaldo, Teddy Atlas and Roberto Duran have been having a laugh.
David Haye has one of his girlfriends here with him. IT'S ALL GOING OFF
Opetaia is clearly up on the scorecards and cruising to a victory.
But the Aussie has extremely high standards and will no doubt be disappointed with his display so far.
Briedis, despite being outclassed, is still chipping away - albeit with singular telegraphed shots.
Joe Cordina's career at super-feather looks over after Anthony 'Apache'Cacace took his scalp and IBF world title.
The Welsh Wizard looked more haggard than Hagrid as he had abused himself to make the 9st 4lb limit.
Cacace dropped him and bullied him before ref Bob Williams finally jumped in - it should have been earlier.
If Cordina cannot safely make the weight in 40-degree Riyadh heat - over three weeks - he won't be able to make it anywhere, if he tries to rebuild.
Up to lightweight or into the Wales history books he goes.
SunSport's Wally Downes Jr is live on the scene at the Kingdom Arena.
And here are his thoughts on Agit Kabayel's upset of Frank Sanchez.
Frank Sanchez, the Cuban prospect who looks like a veteran of the world's hardest paper round, was undone perfectly by Agit Kabayel.
The German pinged the Team Canelo heavyweight all over the Riyadh ring before the referee stopped the beatdown.
Briedis, despite being up there in age, is still a live dog in this.
And the cracking right hand he landed as Opetaia wildly entered range is a testament to that.
A huge shot from Opetaia seemingly shatters the nose of the Latvian, who is bleeding like a stuck pig.
Opetaia is being unusually sloppy with some of his entries, which are telegraphed.
Briedis seems to be more willing to stand and trade, investing in body shots when he closes the distance.
But the Latvian is still off the pace and losing this fight.
Opetaia has really upped the ante here, closing the distance and throwing punches in bunches.
Briedis has yet to go on the front foot and looks content to counter.
But he needs to get himself in range to capitalise when Opetaia leaves himself open with a missed shot.
Opetaia is on the front foot here, controlling the tempo and pace of the contest.
The Aussie corners his fellow former champ and lands a big right hand that draws a big reaction from the crowd.
But Briedis eats it like a packed lunch and goes back to looking from counters from range.
The bell goes. Opetaia is two rounds up, IMO,
Opetaia is happy to operate on the outside and look to feint his way in.
Neither man has thrown or landed anything of note, although Breidis is having his moment controlled by the Aussie.
The bell goes. Round one to Opetaia, IMO.
Footie icon and Brazil star Neymar is in the house for the big fight.
And he wasn't shy in giving his prediction for the bout.
Anthony Cacace has pulled off an INSANE upset by stopping Joe Cordina to become the IBF super-featherweight title.
And he's done it at the age of 35!
Fairytale stuff from the Northern Irishman, who stopped Cordina in the eighth round to send his friends and family back home in Belfast into a state of ecstasy.
The sheer output of Cacace is something else.
He's been absolutely relentless with his pressure, which is slowly but surely sapping the energy and heart of Cordina.
Cordina lands his best punch of the round - a good straight right - seconds before the bell.
