Wilder has the right to a third bout with Fury after the Briton won their rematch at the MGM Grand in February to claim the WBC title.
December 19 had been talked of as a potential date for their next battle, but no agreement has been reached and Fury's promoter, Frank Warren, said the 32-year-old is not prepared to wait until next year to step into the ring with Wilder again.
With Dillian Whyte able to enforce a mandatory fight for the WBC heavyweight title if he beats Alexander Povetkin on Saturday, Fury is running out of patience with Wilder.
He posted on Instagram on Thursday: "@bronzebomber where you at mush? The clock is ticking!! I’m not gonna wait for ever!!!
"There is other bums in the division that I want to eat for breakfast."
It was revealed in June that Fury and IBF, WBA and WBO champion Anthony Joshua had agreed terms for a two-fight deal.
Joshua was due to put his titles on the line against Kubrat Pulev on June 20, but the fight was postponed due to the coronavirus pandemic.
Warren told The Telegraph last week: "Tyson is the fans' favourite and the most famous boxer in the world. I want the best for him. I want him to come away from this sport having been the best of his generation. He has to fight Anthony Joshua."
Warren added: "We talk about the Dillian Whyte fight and all the rest but AJ is the only fight fans are praying for. The fight the fans want is those two facing each other.
"That fight should be in the UK and we should be moving heaven and earth to make it work here. I don't want to take that fight on the road.
"Kubrat Pulev has got a contract to fight Joshua and Tyson will fight this year, but the fight after that should be AJ.
"I hope it's for the four belts, but if it's not, it's not. The belts are fantastic, but if that gets in the way of making the fight happen then forget the belts. At the end of the day, fans will be buying tickets to see these two fighters meet, not the belts."
Wilder will put his WBC belt on the line against challenger Fury in the second instalment of their rivalry on Saturday after the pair fought out a contentious draw in December 2018.
Fury (29-0-1) was almost 50 pounds heavier than Wilder (42-0-1) in the first meeting and the former WBA, IBF and WBO champion carries another huge weight advantage heading into the MGM Grand showdown.
Stepping onto the scales on Friday, British boxer Fury weighed 273 pounds, up from his 256.5lbs-weight in 2018.
Meanwhile, American star Wilder – who was 212.5lbs for the first bout – tipped the scales at 231lbs.
"I just told him, '24 hours, 24 hours'," Wilder said on Saturday. "He's nervous, nervous energy as always.
"At the end of the day, we're heavyweights. So it doesn't really matter about the weight."
Fury added: "The weight's not a problem. It's 273 pounds of pure British beef."
The Nevada State Athletic Commission (NSAC) banned a face-off between Wilder and Fury on Friday.
It came after Wilder and Fury's pre-fight news conference on Wednesday erupted into pushing and shoving as security intervened to keep the fighters apart.
In December 2018, the pair fought out a controversial split draw at the Staples Center in Los Angeles.
Wilder knocked Fury down twice – in the ninth and 12th rounds – yet he beat the count on both occasions.
Defending WBC heavyweight champion Wilder has since revealed Fury kept muttering "dosser", seemingly as a distraction tactic, during the bout.
The 31-year-old Briton has since used the phrase "you big dosser" consistently while calling out Wilder and other fighters, including during a short stint in WWE in 2019.
On Thursday, Fury attended a media gathering wearing a suit embroidered with the catchphrase – an insult he says he intends to use again at the MGM Grand Arena on Saturday.
"Yes, I think I'll be using 'the dosser' again in this fight," Fury told Omnisport. "I've got my 'big dosser' suit on.
"At any given moment I'm going to be pulling out the 'big dosser' line in the fight, don't worry about that."
This will be Fury's third fight in Vegas, a city where he intends to see out his professional career within the next two years.
"Most definitely," Fury said when asked if relocating to Vegas, and bringing a large contingent of support with him, had helped add extra motivation following his comeback.
"I look out and there are thousands of fans who have travelled, British and from all over the world, to see this fight."
Talks over a fight between Fury and Joshua fell through, but there will be another all-British heavyweight battle in London.
WBC champion Fury will defend his title against Chisora, who he beat when they first met in 2011 and got the better of again almost eight years ago.
Fury intends to fight Oleksandr Usyk in a bid to become the undisputed world heavyweight champion in the first part of 2023, but next up will be Chisora.
The unbeaten 'Gypsy King' earned a unanimous decision when he fought Chisora for the first time and had his arms raised again after his fellow Englishman was retired by his corner at the end of the 10th round in their rematch at Wembley.
Fury, 34, insisted he had retired after stopping Dillian Whyte in April, but it was no surprise when he made a U-turn to resume his career.
Unbeaten in 33 fights, the 34-year-old will be a strong favourite to beat Chisora for a third time.
The 38-year-old Chisora stopped Kubrat Pulev in his last bout at the O2 Arena in London, taking his record to 33 victories and 12 defeats.
WBA world champion Daniel Dubois will make a first defence of his belt against South African southpaw Kevin Lerena on the undercard.
Frank Warren, Fury's promoter, said: "I am thrilled to be delivering a Tyson Fury world title defence in front of the British fans in London. Tyson clearly conquered America across his trilogy with Deontay Wilder and there is also huge demand to stage his fights from sites across the world.
"Tyson wanted to fight in his home country again this year following his special night at Wembley Stadium in April. This brings us to the magnificent Tottenham Hotspur Stadium and a match against an old rival in Derek Chisora.
"Derek, also a big favourite with British fans, has reinvented himself in recent years and Tyson has long stated his wish to fight him for a third time.
"Tyson can't afford any slip-up in this fight as he has the much-publicised undisputed match-up with Usyk in the new year which we're really looking forward to."
Fury has made a series of U-turns on his decision to retire following a sixth-round stoppage of Dillian Whyte in April, and originally sought a unification fight against Oleksandr Usyk – who beat Joshua in Saudi Arabia last month.
However, the Ukrainian's reluctance to fight before the end of 2022 led Fury to offer Joshua the chance to face off for the WBC heavyweight belt.
On Tuesday, Joshua's management team 258 revealed the terms of the fight had been agreed last week, only for the passing of Queen Elizabeth II to delay confirmation.
Warren, who handles Fury's fights, says there is still work to be done on the bout – which will seemingly take place on December 3 – but does not anticipate any issues.
"The contracts are on their way," Warren told talkSPORT on Wednesday. "I'm not going into great detail about this, because we saw what happened last time around with people making statements and so forth, and it all fell apart.
"This fight won't be on until it's signed, but everybody wants it to happen.
"The basis of the deal, 90 per cent of what counts, is okay, 10 per cent we've got to sort out. There aren't any obstacles in the way, so hopefully very quickly we can get it over the line.
"When you're a promoter, you're an optimist. That's what you do. You're in the business of trying to make events happen, so we're all excited by it.
"I'm excited about it as a fight, because I always felt that Tyson has the beating of AJ, and now we're going to find out if we get this over the line."
While Fury is unbeaten in his 33 professional fights, winning 32, Joshua has suffered three defeats in his last five bouts.
The WBC heavyweight championship will be on the line in Saturday's meeting at Tottenham Hotspur Stadium, with the two Brits locking horns in a trilogy bout.
Few had this fight top of their wishlist, with fans instead keen for a unification bout against Usyk or a 'Battle of Britain' clash with Anthony Joshua.
However, a meeting with Usyk remains in the pipeline, Arum has said, though he has warned Chisora has the credentials to cause Fury problems.
"I don't see any reason why the Usyk fight with Tyson Fury can't be made speedily," he said.
"That fight will happen next unless Mr Chisora lands his punch. Don't discount Chisora. Chisora's a hell of a fighter. He has a tremendous punch.
"He gave Usyk life and death. You can't in this business count your chickens before they're hatched. Chisora will answer back. It's a great, great fight. It really has a lot of interest.
"Two big heavyweights getting in the ring trying to knock each other's head off. Nothing is more exciting."
Underdog Chisora is looking to make a statement with a knockout win against Fury and made it clear he will come out of the blocks flying with an aggressive approach in the opening rounds.
"On Saturday I'm going to go to war. There's no two ways about it. I want to take what's his and make it mine. Physically and mentally," he declared.
"I can guarantee you, you are going to love the whole show we are going to put up. It's not going to be stinker, it's going to be a great fight.
"We want to give you the best first round in the heavyweight game forever. We need the first round to be electric, so the place will be buzzing. "I'm prepared to do it. We shook on it."
The Briton downed Derek Chisora in the pair's trilogy bout on Saturday to maintain both the WBC title and his undefeated record.
Fury squared off with Usyk, who saw off Anthony Joshua for a second time earlier this year to retain his WBA, IBF, WBO and IBO belts, after his victory.
Previous hopes for a unification bout over the years have often been hindered by the contradictory mandatory challengers various governing bodies have in place, but Sulaiman is keen to see the pair cross paths imminently.
"This is a perfect time to do a unification," he told Sky Sports News on Monday. "At this time we have no mandatory contenders, so this is a perfect moment for the unification.
"Hopefully it will not get to that point [that we have another mandatory challenger] and the four organisations will accept to sanction the ultimate undisputed fight.
"Mandatories are a complicated process. Each organisation has their own rules, their own agendas, but the importance of this fight is far beyond any organisation.
"We're supporting it, and we'll do everything possible to make sure it takes place."
Fury has indicated he could fight fellow Briton Joe Joyce next, and though Sulaiman acknowledges he would not prevent such a bout, his priority remains setting a match up with Usyk.
Joyce has put together a series of impressive performances to move himself to the verge of title contention, and Sulaiman would not stand in the way of an all-British matchup with Fury.
"No [issue with a Joyce fight]. At this time, as I mentioned, we don't have the mandatory contender yet," he added. "As soon as we have one, we can set timelines. Our ultimate goal is to have a unification."
Usyk retained his WBA, WBO and IBF titles, and also claimed the Ring Magazine belt with a split-decision victory over Joshua on Saturday to take his record to 20 professional bouts undefeated.
WBC champion Fury appeared to reaffirm his retiremenet ahead of the fight, but subsequently suggested promoters and fans "get [their] cheque book out" after the Ukrainian's win.
Warren, who handles Fury's bouts, has suggested the pair could square off next - and finally deliver the division's first undsputed champion since 1999.
"He and Usyk would be a really good fight," Warren told BBC Radio 5 Live. "It's a fight that I think will be made because both teams would like to see that happen."
Britain's Lennox Lewis beat Evander Holyfield to become the last undisputed heavyweight champion over two decades ago, but there has not been a bout with all four belts on the line since the WBO title was included in 2007.
"Usyk said after the fight that it's the only fight he's interested in, and it's certainly the same case with Tyson," Warren added.
"It's just a matter of where it will generate the most income because it's a unique fight, a historic fight.
"It's the first time for God knows how long that the four belts are on the line. Both fighters are undefeated. The whole world of boxing will be captivated by this fight."
Warren has also not ruled out seeing the long-awaited clash between Fury and Joshua, though the likelihood of such a fight following the latter's third defeat in his past five fights seems questionable.
Joshua first lost the WBA, WBO and IBF titles to Andy Ruiz Jr, though despite winning them back in the rematch, subsequently lost them to Usyk again last year.
The prospect of an all-British unification bout between Joshua and Fury was floated at multiple points during their reigns but ultimately never materialised, and Warren said Joshua will have to win some more fights before he can be considered a contender for Fury.
"If AJ manages to get a couple of wins under his belt - and I believe Tyson will beat Usyk - that may be a fight to be made," Warren added. "But AJ's got to re-establish himself before you can even think about fights like that."
Paul knocked out Tyron Woodley on Saturday, with the latter having stepped in at short notice for a rematch following Tommy Fury's withdrawal.
After the win, Paul expressed his desire to get in the ring with either Jorge Masvidal or Nate Diaz, both UFC stars.
However, the 24-year-old has now turned his attention to five other candidates, including Fury's brother, heavyweight champion Tyson.
Also on the list is one of boxing's greats, Floyd Mayweather Jr, who has not fought since 2017, though the 44-year-old has previously been touted as a possible exhibition opponent for Paul's older brother Logan.
Canelo, the first boxer in history to become an undisputed champion at super middleweight, was also named on Paul's hit list, as was the legendary Mike Tyson.
UFC boss Dana White, meanwhile, was another inclusion.
There is some animosity between the pair, however, with Paul previously criticising White's treatment of UFC's fighters.
"I make more than every UFC fighter f****** combined, including Conor [McGregor]. Y'all work for f****** Dana, y'all work for WME, Endeavor, that's who you work for," he said on his brother Logan's podcast.
"I make more than all of you silly m*****f******. Why would I go into the UFC? Sign a contract and give away rights. I own my content, I own my platform, I own everything. They don't own s***, they are literally employees."
Paul also said he would knock White out, to which the UFC boss, in an interview with MMA Junkie, replied: 'It actually makes sense. I'm 52 years old. I'm in the age bracket of guys he fights, so yeah, I could see him wanting to fight me. All he fights are 50-year-olds."
The highly-anticipated second bout appeared to be in danger of being delayed when Fury suffered a deep cut during the third round of his points win over Otto Wallin in September.
Fury later claimed he needed 40 stitches for the wound and it was noted by Wilder that he wore sunglasses during Wednesday's news conference.
The Briton's cutman Jacob 'Stitch' Duran has since revealed Fury has had mesh web inserted into the soft tissue above his eye but stressed "it won't be an issue" in Las Vegas on Saturday.
However, Wilder believes the problem is more serious than Fury or his camp are letting on.
"That's definitely something that I'm targeting," he said.
"When a fighter has a wound that, we feel, is not all the way healed - no matter what he says - because as a fighter being in here, as a veteran being in the game, you see so many different things and you can acknowledge a lot of things and you know.
"It's like him coming to the press conference, he changed up something. He wore a hood and he wore glasses. He's covering up something. Fury, we know your secrets. We know what's going on.
"That was just one of those things where he was just trying to cover up.
"He didn't want me to see how severe the cut was. You hear all the rumours as well that he didn't allow his sparring partners to hit him in the face, they just did body sparring and different things like that.
"That just shows a strong indication that something happened in that camp, something happened with his eye.
"Credit to him, he's a warrior, he's still coming, he's still trying to cover it up and come Saturday night is going to be ready to show up and present himself as, what he calls himself, the lineal champion."
Wilder will be denied the chance to have a closer inspection of Fury's eye on Friday as the traditional pre-fight face-off at the weigh-in has been cancelled after the pair confronted each other on stage on Wednesday.
WBC champion Wilder, whose record stands at 42 wins and one draw from his 43 fights, will be hoping to make the 11th successful defence of his title.
The only time he did not emerge victorious was in the original meeting with Fury back in December which ended in a contentious draw.
Of Fury's 30 fights, that was the only bout he has not won too.
Fury (31-0-1) stayed undefeated thanks to his 11th-round KO against Wilder in Saturday's blockbuster trilogy in Las Vegas.
In an all-time epic bout, Fury was dropped twice but the British star got the better of Wilder (42-2-1), who showed incredible courage to make it to the penultimate round having appeared out on his feet.
After the slugfest, Fury said: "Like the great John Wayne said, I'm made of pig iron and steel, baby!
"I took some big shots but my lord and saviour helped me up and kept me going. It was a great fight tonight and it's worthy of any trilogy in the history of the sport."
"I was down a couple of times, I was hurt, Wilder is a strong puncher," said Fury, who landed some thunderous blows to the head of the American.
"It was a great fight. I will not make any excuses, Wilder is a top fighter, he gave me a run for my money. I always say I am the best fighter in the world and he is the second best.
"Don't ever doubt me. When the chips are down I can always deliver."
Fury added: "I'm now the greatest heavyweight of my era, without a doubt. Number one, numero uno. Look what I've done.
"I've came to America my last six fights and fought the most devastating puncher in the history of our sport. Not once, not twice, but three times. Danger, danger man."
After a contentious split-decision draw in the first meeting back in December 2018, the rematch saw Fury take the judges out of the equation with a dominant performance, forcing a seventh-round stoppage that not only saw Wilder lose the WBC title but also his unbeaten record as a professional.
The pair put on an instant classic on Saturday but Wilder appeared unwilling to pay respect to Fury as he swiftly left the ring post-fight.
"I'm a sportsman; I went over to show some love and respect and he didn't want to show it back," Fury said. "I'll pray for him so God will soften his heart."
"I said, 'Well done'. And he said, 'I don't wanna show any sportsmanship or respect.' I said, 'No problem'."
"Very surprised [by] that," Fury continued. "Sore loser, an idiot. Do you know what? To be a top fighting man, you've got to show guts and respect and he couldn't do it tonight. And that's it."
A fight date had been agreed for April 29 at Wembley Stadium with progress made in recent weeks after the pair had agreed to a 70-30 purse split in favour of Fury.
However, the two sides have since been unable to match up on other key details such as a rematch purse split, with Ukrainian fighter Usyk now said to have shut down his training camp.
"No matter how much Usyk compromised, he was pushed for more," Usyk's manager Egis Klimas said, according to reporter Steve Kim.
WBA president Gilberto Mendoza previously set a deadline of April 1 for the fight to be agreed, with the latest setback likely to scupper any chance of reaching an agreement before that date.
Usyk, who has the WBA, IBF and WBO heavyweight titles, now looks set to return in June or July in a mandatory defence against Daniel Dubois.
The 36-year-old was the undisputed champion at cruiserweight before moving up to heavyweight.
Back-to-back victories against Anthony Joshua in September 2021 and August 2022 saw him capture and retain the three belts.
Fury, who last fought Derek Chisora in December, holds the WBC heavyweight title. It is unclear who or when he will next fight.
The Briton had previously announced he would be entering a social media blackout as he began training camp for the Usyk fight.
He had made numerous demands in order to make the fight happen and suggested his opponent only warranted 30 per cent of the total fight purse.
Usyk had agreed to this proposal but also requested that Fury donate $1million to relief efforts in Ukraine.
The bout would have marked the first crowning of an undisputed heavyweight title in the four-belt era.
Photographs of unified IBF, WBA and WBO champion Joshua talking to WBC king Fury as the latter passed him in a car at the Spanish resort again set tongues wagging over a long-mooted meeting in the ring.
Fury must first come through a third encounter with American knockout artist Deontay Wilder, who he dethroned spectacularly in February, while Joshua has an obligation to IBF mandatory challenger Kubrat Pulev, who he was slated to meet in June at Tottenham Hotspur Stadium before the coronavirus pandemic struck.
Speaking to Sky Sports, Joshua acknowledged a fight with Fury has to happen in the near future and poked some gentle fun at his fellow Briton.
"It's only right that me and him will bump heads soon. We're going to put on a great show for the British public, the world public," Joshua said.
"It's going to be a massive fight. I'm looking forward to it.
"What was cheeky about the situation [in Marbella] was he couldn't even get out of the car and offer me a drink.
"I don't know how he saw me because I had my mask on, my hat on and everything.
"He's obviously got his eye on me. He's probably following me around, he blew his cover!
"All respect to him. He was with his wife as well, all respect to her. They're a humble family."
Joshua attended a Black Lives Matter rally in his hometown of Watford on crutches last month, although he reported encouraging progress from a knee complaint.
"I think you saw I bumped into Tyson Fury last week. I'm on my feet, I'm going for my 10,000 steps," he added.
"I'm in the gym, I'm standing up, I'm smashing the heavy bag, smashing the bag. The knee's good."
Both combatants are widely thought of as the best heavyweights in their fields but while mixed martial artist Ngannou is renowned as a fearsome puncher, he is ultimately stepping into Fury’s world.
Here, the PA news agency looks at some of the talking points arising from a bout that has excited some, bemused many others and has been dubbed a clash to determine the ‘baddest man on the planet’.
Was this announcement expected?
The pair have traded barbs on social media for many months so it was not a total surprise, but it is underwhelming to a lot of boxing fans. Fury, the WBC champion, has seen negotiations for fights against WBA, IBF and WBO titlist Oleksandr Usyk and British rival Anthony Joshua collapse. An undisputed world title showdown against Usyk falling by the wayside is especially disappointing for the sport with each fighter blaming the other for talks breaking down. With Usyk and Joshua now tied up, Fury’s team have argued he was out of credible challengers so in steps Ngannou, who has risen to the top of mixed martial arts but never boxed professionally.
Surely there was someone more capable for Fury?
Usyk will defend his world titles against mandatory challenger and Fury’s promotional stablemate Daniel Dubois while Joshua has elected for a rematch against London rival Dillian Whyte next month. Fury was also linked with former world champion Andy Ruiz Jr, who seems to be leaning towards a fight against Deontay Wilder. Fury taking on a novice will grate with traditionalists but the WBC granted the self-styled Gypsy King permission to fight Ngannou without the title being at stake because there is “no official challenger”.
Is this a gimmick?
While Fury will not be defending his world title, his team have insisted this is not an exhibition. There will be three ringside judges present and the 10-point must system – the scoring criteria used in all of professional boxing – is being implemented. It remains unclear how many rounds are scheduled and if this will count towards Fury’s professional record. Fury’s co-promoter Frank Warren called this a ‘game changer’ but MMA stars crossing over into boxing has been increasingly prevalent since Conor McGregor faced Floyd Mayweather in a lucrative battle.
What is Ngannou’s story?
Ngannou left extreme poverty in his native Cameroon, where he worked in a sand quarry from the age of 10, to pursue a boxing career in Europe. He ended up homeless in Paris in his mid-20s but his potential was recognised in a gym and he was persuaded to switch his focus to MMA, rising through the ranks to become top dog in the UFC. Ngannou was stripped of his title in January amid an acrimonious departure from the UFC and has signed with the Professional Fighters League on an MMA deal only. This has opened the avenue for Ngannou to pursue his first true passion.
What chance does Ngannou have?
MMA fighters have not transitioned well to boxing, with McGregor losing to Mayweather in 2017 while Ben Askren, Tyron Woodley and Anderson Silva have been beaten by YouTuber-turned-boxer Jake Paul. Going in Ngannou’s favour is his devastating power – he has highlight-reel knockouts few others can match – but the 36-year-old will be wearing bigger gloves against Fury. The Briton knows how to handle formidable punchers having beaten Wilder twice and has promised to stand toe-to-toe with Ngannou. This may open the door fractionally for Ngannou but in any situation he is a massive underdog. Fury is superb technically, can adapt to any situation and has shown he possesses frightening power himself.
What next for Fury, assuming he wins?
A frequent criticism of boxing is it is hard to distinguish who is the best fighter in a weight category given there are four major world titles although the sport has recently got its act together. There have been several undisputed world title fights in the past couple of years but the heavyweight division is the anomaly. Irrespective of who is to blame, this does not reflect well on anybody. Fury, who has attracted the most criticism, argues he is the greatest of this era but fights against Derek Chisora and Ngannou do not pass the muster. No ifs or buts for Fury, Usyk must be next.
Garcia (21-0) was reported to be in talks for a bout against Filipino great Pacquiao (62-7-2).
The American seemed to confirm that fight was going ahead in an Instagram post on Sunday.
"A dream turned reality," Garcia wrote.
"It's an honour to share the ring with @mannypacquiao. I will always respect what you did in and out the ring.
"Here's to the best man winning."
Garcia fought on January 2, beating Luke Campbell to win the interim WBC lightweight title.
Pacquiao, 42, was last in action in July 2019 in a split-decision victory over Keith Thurman to win the WBA welterweight crown.
Fury and Usyk are set to meet in a fight that is tentatively scheduled for early 2024.
Widely considered as the world's leading heavyweight, Fury was pushed to the limit by UFC brawler-turned-boxer Francis Ngannou in a non-title bout in Riyadh on Saturday.
Indeed, Fury was fortunate to come away with a win, with two judges deciding in his favour.
Ryan Garcia, who is set to fight Oscar Duarte in December, believes the undefeated Fury will still have too much for Usyk, though.
"The Gypsy King, that's it," Garcia told Stats Perform.
"He's the best, the Gypsy King is an unbelievable talent. And he has an amazing personality. He's super, super cool."
Fury's meeting with Usyk will quench a long-held thirst, though despite years of posturing, a battle of the Britons between the 35-year-old and Anthony Joshua is yet to take place.
"I'll be excited to see him versus Anthony Joshua one day, I would want to go to that one that will be huge," Garcia said.
"And that’s the one I would actually be looking forward to more [than Fury v Usyk], to be honest."
Fury, for his part, was honest in his appraisal of his own performance against Ngannou in Saudi Arabia.
"He's given me probably one of my toughest fights in the last 10 years," Fury said. "Francis is a hell of a fighter, strong, big puncher, and a lot better boxer than we all thought he would be.
"He's a very awkward man and he's a good puncher and I respect him a lot."
Fury and Usyk bumped into each other in Riyadh prior to Saturday's fight, with the pair sharing an embrace.
And the duo faced off in the ring following the bout, with Fury saying: "Let's go,"
Usyk added: "Let's go. I'm going to be fighting him, amazing."
Heavily favoured after stopping Adrian Granados in April, 31-year-old Garcia (36-2, 21 KOs) turned in a workmanlike performance over 12 rounds to defeat his Ukrainian opponent.
The only real drama came when Redkach (23-5-1, 18 KOs) appeared to bite the American on the shoulder during the eighth round.
Garcia laughed off the incident, telling Showtime: "He said 'Mike Tyson' when he bit me. I said: 'Ref, he bit me!' That's my first time ever getting bitten in a fight. Things happen, though."
A former two-division champion, Garcia could now look to a meeting with either Manny Pacquiao or Errol Spence Jr.
"Either of those fights I would like to have," he said. "I think my style fits great with both fighters, or even a rematch with Keith Thurman, or Mikey Garcia.”
On the undercard, Jarred Hurd had to contend with boos from the Brooklyn crowd before beating Francisco Santana (25-8-1, 12 KOs) via unanimous decision.
Hurd (24-1, 16 KOs) was jeered during the second half of a forgettable affair despite cruising to a comfortable victory in his first fight since the surprise loss to Julian Williams in May.
Garcia, 21, improved to 20-0 after a huge left hook knocked Fonseca out just 80 seconds into their bout in Anaheim.
The American, who already has 17 knockouts in his career, was thrilled with his victory.
"It was a good performance, it didn't last long," Garcia told DAZN in an in-ring interview.
"I watched a video of Sugar Ray Robinson before coming into this fight, he did a little fake and he caught him with the perfect left hook. When I see Fonseca move that way, I just faked him a little bit and caught him clean with that left hook.
"I was planning for it to go a little longer, I'm not gonna lie, but respect to Fonseca, they're great people."
Jorge Linares and Gervonta Davis have been mentioned as possible next opponents for Garcia.
Linares was also in action on Friday, recording a fourth-round knockout of Carlos Morales to improve to 47-5.
Garcia was awarded the bout 116-111, 116-111 and 114-113 after controlling the second half of the fight – for the WBC diamond welterweight title – at the Ford Center at The Star.
The American, back at welterweight after the first loss of his professional career against Errol Spence Jr. last year, knocked down Vargas in the fifth round.
Garcia is eyeing either a bout with Pacquiao or a rematch with Spence, who holds the WBC and IBF welterweight titles.
"I have great options," he told DAZN.
"I'm ready to get back in with the best, I would love to get an opportunity to fight Manny Pacquiao, I want a rematch against Errol Spence.
"It would be a tremendous fight, I'm a little bit better now at this weight class."
Pacquiao, 41, last fought in July last year, beating Keith Thurman to claim the WBC welterweight title.
Meanwhile, Roman 'Chocolatito' Gonzalez claimed the WBA super-flyweight title with a ninth-round TKO of Khalid Yafai in Texas.
Garcia was crowned WBC interim lightweight champion after a devastating left hook to Campbell's body finished the Englishman off 1 minute 58 seconds into the seventh round.
The 22-year-old lightweight made it 21 straight pro wins in a thrilling contest but it was far from a smooth victory against the 33-year-old in the American Airlines Center.
After the rising star was carried to ringside on a throne, 'King Ry' was dropped for this first time in his career with a stunning left hand from Campbell in the second round.
Garcia offered a quick response and continued as the aggressor, almost knocking Campbell down at the close of the fifth but 'Cool Hand' hit the ropes and was saved by the bell.
The perfectly-placed finishing blow sunk the Olympic gold medallist to the canvas as Garcia recorded a fifth straight knockout since teaming up with gym-mate Saul 'Canelo' Alvarez.
"Yo, I got dropped, this is crazy," Garcia told DAZN.
"I’ve never been dropped in my life. I think I got a little too excited over the moment.
"I knew I was in control.. and I thought I could just crack him, but he cracked me.
"So I had to adjust and just say ‘I’m going to calm down’ because I knew I could beat him.
"I had to get back up and show everybody what a warrior really is like."
