Two former heavyweight world champions collide in Saudi Arabia on Saturday, as former WBC king Deontay Wilder takes on Joseph Parker, who held the WBO title for a period between 2016 and 2018.

The blockbuster clash forms part of the huge ‘Day of Reckoning’ card and is the co-headline event, alongside Anthony Joshua’s meeting with Otto Wallin.

Wilder versus Parker will be the penultimate bout, before Joshua and Wallin face off.

Wilder may have lost his WBC title and unbeaten record to Tyson Fury, but he remains one of the most feared men across boxing.

The American has 43 wins and 42 stoppages, he also has two losses and a draw on his record - all results from his trilogy with Fury.

Parker has 33 wins and three defeats in 36 fights and he is on the rebuild after losing out to Joe Joyce in September of 2022.

The New Zealander has picked up three wins since that defeat, but all of those came against lesser opposition and Wilder is a huge step up for the 31-year-old.

This bout also represents a bit of a step up for Wilder after a period of relative inactivity as this will be just his second fight since being stopped by Fury in the 11th round in 2021.

The Alabama-native was last seen when knocking out Robert Helenius inside the first round in October of last year, as proposed fights with Joshua and Andy Ruiz have failed to materialise.

Tip 1 - Deontay Wilder to win in rounds 1-6 @ 11/10

Wilder only needed a round to end the challenge of Helenius in his comeback fight and there is a good chance he will be able to end his showdown with Parker before the halfway point in Saudi Arabia.

Parker may have recorded three wins in a row since his defeat to Joyce but, with all due respect, those fighters were nowhere near Wilder’s level.

The Kiwi was taken the full distance by Jack Massey, who has spent the majority of his career at cruiserweight, at the start of 2023 then recorded wins over relative unknowns Faiga Opelu and Simon Kean.

That is hardly ideal preparation to fight a knockout specialist such as Wilder, and his performance against Joyce suggests he could be in trouble this weekend.

Parker was stopped in the 11th by Joyce as he was unable to avoid the ‘Juggernaut’, and he is coming up against a far more agile opponent in Wilder.

Joyce is the kind of fighter who will use his size to wear opponents down and earns his stoppage wins via the cumulative effect of a number of blows, whereas Wilder goes hunting for the knockout punch pretty much from the get-go.

Wilder has claimed 42 stoppage wins in 43 victories and four of his last seven victories have come inside the first five rounds.

It remains unclear as to what level Parker is truly at right now after facing lesser opponents in his last three outings, but against Joyce his movement wasn’t good enough to keep him out of trouble and Wilder has far better accuracy than the Briton.

As he always does, Wilder will be focused on trying to land a knockout punch from the first bell and there is a good chance he will be able to connect before the end of the sixth round, and it is hard to see Parker beating the count if he is caught flush by the heavy-hitting American.

Tip 2 - Deontay Wilder to win in rounds 1-2 @ 13/2

The ‘Bronze Bomber’ is a fairly one-dimensional fighter as he will rarely attempt to outbox or outthink his opponent, instead he essentially lasers in his focus to landing a knockout blow from the off.

Technically, Parker is the superior boxer in terms of skill set, variation and general ring intelligence, but that could count for very little when faced with a puncher as powerful as Wilder.

Parker likes to fight off the back foot and keep his distance before picking his moments to engage and that sort of tactic may ultimately play into Wilder’s hands, as he relentlessly searches for that fight-ending shot as he will be ready to strike whenever the New Zealander moves into range.

There is clearly a chance that Parker’s tactical nous will see him evade serious trouble, but Wilder should come out all guns blazing from the off and he only needs one big shot to end this contest, so a small stake on the American claiming another early finish is worth some consideration for anyone looking for a big price option.

Dmitry Bivol returns to the ring after a 13-month absence this weekend as he defends his WBA light heavyweight title against Britain's Lyndon Arthur.

Bivol will make the 11th defence of his crown on the undercard of the "Day of Reckoning" in Saudi Arabia, which pits some of the world's best heavyweights against each other.

The Russian was last in the ring in November 2022, while Arthur was last in action in September, so he goes into the contest with sharpness on his side.

Bet 1 - Dmitry Bivol to win @ 1/20

Light heavyweight king Bivol is back and ready to prove a point as he fights for the first time in 13 months this week.

The 32-year-old outclassed Gilbert Ramirez in November last year at the Etihad Arena in Abu Dhabi, but he has since been on the sidelines.

Bivol underwent surgery in April to try and stop the pain in his right hand, which was preventing him from training effectively. He has had reservations about throwing his right hand in previous fights, but he is now confident he can land a variety of punches without any pain.

Considering Bivol has had an injury to worry about, he has not done too bad for himself.

He has yet to lose as a professional and has 11 knockouts from 21 contests, although he has not recorded a stoppage victory in five-and-a-half years.

Still, during that time, he outclassed pound-for-pound superstar Saul 'Canelo' Alvarez over 12 rounds, using his size and reach advantage to devastating effect.

While some will look at this break as damaging, Bivol is adamant he is now fresh and fully healed ahead of a busy few months, but he will not be overlooking Manchester's Arthur.

Bivol is planning bigger and better things in 2024, and he should be able to dictate the early pace of the fight before recording a stoppage victory.

Bet 2 - Dmitry Bivol Draw No Bet @ 1/25

Like Bivol, Arthur is 32, but he has not had as much success in his career and will be fighting for the third time this year. He claimed the IBO light heavyweight title last time out, beating Braian Nahuel Suarez in the 10th round.

At 6ft 2in, Arthur is the taller of the two fighters, and he will need to use every inch of that to try to dictate from distance. In what is his first legitimate world title contest, Arthur is fighting on the biggest card of his career against one of the world's best boxers.

The Manchester fighter was expected to reappear in February, but he has jumped at the chance to test himself against the very best, and he has already pulled off a shock win in the past.

Arthur faced Anthony Yarde in December 2012 and won a split decision to stun his British rival, but he was put back in his place 12 months later when Yarde stopped him in the rematch.

Since that defeat, he has got his confidence levels back up with four successive wins, including three knockouts, but none of those victories came against anyone with Bivol's skill-set.

Sixteen knockout wins suggest Arthur possesses the power to earn Bivol's respect, but the question is, can he land a powerful punch?

Bivol's absence from the ring may be to his detriment, and if he starts slowly, Arthur needs to jump on him and try to unsettle him as best he can.

However, nothing Arthur throws at Bivol will come as a surprise, as he has ruled supreme at the top of the division for six years.

Bivol's ultimate goal will be an undisputed fight against the winner of Artur Beterbiev & Callum Smith once they clash in January, and this bout with Arthur should present him the perfect opportunity.

While he has not had a stoppage win on his CV for many years, Bivol's right hand should be better than ever, and we know Arthur is vulnerable after being stopped by Yarde.

While Bivol is not as explosive as Yarde, he should be able to wear Arthur down, who will do all he can to stay in the fight until the final bell.

A late stoppage looks the way to go in this one, with Bivol setting himself up perfectly for a shot at the undisputed crown in 2024.

Daniel Dubois is on the comeback trail on Saturday night with a match-up against Jarrell Miller as part of the stacked ‘Day of Reckoning’ card at the Kingdom Arena in Riyadh.

Dubois came close to ending Oleksandr Usyk’s reign as heavyweight world champion in his last bout, and is now looking to engineer another world title shot.

The Briton had Usyk down in the fifth round in Wroclaw in August but his body shot was controversially ruled a low blow. With Usyk given the maximum time to recover (he used just under four minutes of the five he had been allocated), the Ukrainian went on to win via a ninth round stoppage.

Miller is perhaps best known for a world title fight against Anthony Joshua that never was in 2019 after he tested positive for a banned substance. The American returned to the ring after a four-year absence in 2022 and has recorded three wins since, but Dubois represents his toughest assignment to date by some distance.

Tip 1 - Fight To Go The Distance No @ 11/20

This fight is scheduled for 10 rounds and it is the first time Dubois hasn’t been involved in a 12-round bout since his seventh professional outing in 2019. However, none of the Londoner’s bouts have ever reached an 11th round, and it seems unlikely that his clash with Miller will require the judges.

Dubois has put together an 18-2 record and he has a knockout rate of just under 95 per-cent. The 26-year-old has been taken the full distance just once, and that was a 10-round affair with experienced old pro Kevin Johnson back in 2018. Dubois’ two defeats have also come via stoppages, and Miller is also a fighter who rarely hears the final bell ring.

Miller has 26 wins, no defeats and one draw on his own record and he has claimed 22 stoppage victories during his career, while only one of his 27 bouts has required more than 10 rounds.

Both of these heavyweights clearly carry plenty of power and chances are one will win via a stoppage, potentially in the second half of the fight.

Tip 2 - Dubois To Win By KO, TKO or DQ @ 5/4

Miller is coming into this fight with an unbeaten record and he would have won the one draw on his CV had he not been deducted two points for pushing in a four round contest in the early stages of his career,

However, ‘Big Baby’ has never managed to fight at the highest level, for a variety of reasons, and Dubois represents a step up in class for the 35-year-old.

Dubois has been in some high-profile fights and he raised his reputation with his performance against Usyk despite the defeat. ‘Dynamite’ felt the blow that floored Usyk in the fifth shouldn’t have been ruled a low shot, and in his mind he probably feels he should be a world champion right now.

Whether that is true or not is up for debate, but what Dubois did prove during his bout with Usyk is he can land a big shot on the most elusive fighter in the heavyweight division and he should find Miller a far easier target to hit.

Dubois perhaps has a few questions to answer over his own desire as there was the suggestion he perhaps gave up a bit too easily against Usyk and against Joe Joyce in 2020.

Those comments could be considered unfair, however, as he had sustained a serious eye injury in the defeat to Joyce and by the time Usyk stopped him he was getting caught regularly without landing anything meaningful himself.

This fight against Miller is a chance at redemption in a way and an opportunity to work towards another title bid, and he will be eager to make a statement in Saudi Arabia by recording an early finish.

Miller remains a bit of an unknown quantity and is untested at world level, with his biggest wins coming against Mariusz Wasch in 2017 and Tomasz Adamek the following year.

There is an element of uncertainty here but Dubois clearly looks the more likely winner, given the level of opponent he has faced - and beaten - previously, and he should be able to get the job done inside the distance against the veteran American.
