Kieron Conway and George Liddard will put their futures on the line as the former bids to defend his British and Commonwealth titles from London's York Hall live on DAZN.
'Too Class' added the Lonsdale Belt to his collection by stopping Gerome Warburton inside four rounds back in May to make it straight middleweight successes.
Liddard however arrives brimming with a confidence that he can dethrone him, and reaffirm his credentials as one of the country's most promising boxing prospects.
But just how did both men come to this major face-off? DAZN News looks at the last five fights of each fighter and profiles what has guided them to this latest opportunity.
It's been one-way traffic for the incumbent champion since a 2022 loss to Austin Williams, his third career reverse - and with the biggest prize of his career claimed too.
Conway, a former Lonsdale challenger at super-welterweight, took a points win over Jorge Silva in Nottingham the following February to get himself back on track.
He followed it up with TKO triumphs against Linus Udofia and Ainiwaer Yilixiati, before he edged Ryan Kelly via split decision to take the Commonwealth belt.
Then, in May this year, Conway ruthlessly outclassed Warburton inside four rounds at the Copper Box, to take the vacant British title and cement his superb turnaround.
Built on arena undercards across the start of his career, the imperious Essex star will hope to carry his rich form across into the biggest fight of his career thus far.
Liddard fought five times alone last year, with a points win over SA Smith in June followed by TKO success against George Davey and Omar Nguale Llunga.
He then found himself taken the distance by Derrick Osaze this January, in the longest fight of his career thus far, helping to bank some crucial championship rounds.
Finally, he dismissed Aaron Sutton inside five at the Copper Box in May, on the same bill as Conway - and moved himself into prime position as his challenger.
Joseph Parker and Fabio Wardley fight on Saturday, October 25, to become the WBO mandatory challenger to Oleksandr Usyk. Watch the fight and undercard live and exclusive on DAZN PPV.
