After years of trash-talking and false promises, British stars Kell Brook and Amir Khan will finally cross paths this weekend as they look to settle their feud in Manchester.
The duo have avoided each other for the majority of their careers, but with the pair close to retirement, they are finally going to settle the score in front of a packed crowd in Manchester.
British fight fans have been spoiled of late, with two all-British grudge matches taking place before the spring.
Chris Eubank Jr outclassed Liam Williams earlier this month, and now it is Khan and Brook's turn to trade leather.
Both men have already achieved everything they can in the sport, winning world titles, but it is fair to say that they are both at the tail-end of their careers.
Khan's last competitive fight took place in April 2019 when he was stopped by Terence Crawford, while Brook also lost to 'Bud' in November 2020.
The loser is likely to retire for good, while the winner might have an outside chance of one final crack at a world title.
Amir Khan - 39 fights, 34 wins (21KOs), 5 defeats
Kell Brook - 42 fights, 39 wins (27KOs), 3 defeats
The main card is due to start at 6pm GMT, and the main event ring walks are expected to take place at 10pm GMT.
Saturday's fight will take place at the AO Arena in Manchester, which is somewhere both fighters have boxed on numerous occasions.
Natasha Jonas vs Chris Namus
Charlie Schofield vs Germaine Brown
Bradley Rea vs Craig McCarthy
Frazer Clarke vs TBA
Viddal Riley vs Willbeforce Shihepo
Adam Azim vs Jordan Ellison
Hassan Azim vs MJ Hall
Abdul Khan vs Ricky Starkey
Ibrahim Nadim vs Taka Bembereb
Sheffield fighter Brook is priced at 4/7 to win Saturday's bout, while Khan can be backed at 11/8 to win in front of his local crowd.
At 35, both Khan and Brook know that father time is not too far away, and both fighters could be lapping up the pre-fight hype for the final time.
Khan, a former welterweight world champion, has shared the ring with some of the best boxers of his generation, but Brook, an ex-unified super-lightweight champion, has always maintained he could beat him.
The duo avoided each other during their prime, but as long as there are no last-minute hiccups, the chapter will finally be written this weekend.
Even though they are reaching the end of their respective careers, both have always shown a killer instinct in the ring. With 48 stoppage wins between them, both carry the power needed to stop the fight and it looks like the bout will end before the 12 rounds, available at 4/7.
Bolton's Khan has been on the wrong end of some vicious knockouts during his career and that will give Brook every faith he can stop his domestic rival.
Breidis Prescott was the first to put Khan on the canvas in 2008, while Danny Garcia, Saul Alvarez and Terence Crawford have also sent Khan packing inside the distance.
Considering the level of opposition, that is nothing to be ashamed about, and Brook, who is 13/10 to win by stoppage, has also taken his fair share of punishment.
"The Special One" dared to be great earlier in his career when he stepped up two weight divisions to challenge Gennady Golovkin, the most feared middleweight fighter on the planet.
Brook's plan backfired, though, as he broke an orbital bone before then, suffering the same injury during his defeat to Errol Spence Jr.
His injuries have derailed his plans to conquer the world for a second time, and a lack of motivation has not helped his cause.
However, Brook's hatred for Khan is well known and he would love to send his rival into retirement before he hangs up the gloves and while Khan has his shortcomings, Brook's ability to compete at the highest level is doubtful.
Khan has done everything he can to prepare for Saturday's bout, spending the majority of his training camp in the USA.
The high-altitude training at Crawford's gym has helped his fitness, and his world-class sparring against a former rival could prove the difference as he tries to record a famous victory.
Thankfully for the former Olympic silver medallist, he does not look like he has lost his speed, and if he can fight in bursts, there's every chance he can stop Brook inside the distance at 7/2.
