Jaime Munguia and John Ryder are set to go toe-to-toe in an intriguing super-middleweight contest this weekend, and we've got everything you need to know ahead of the showdown.
Munguia (42-0, 33 KOs) produced an excellent display when beating Sergiy Derevyanchenko in a fight of the year contender back in June.
Ryder (32-6, 18 KOs) travelled to Mexico to take on the elite-level Canelo Alvarez last time out and the British fighter put up a credible performance to take the Mexican the full 12 rounds on his home turf.
Can Ryder produce a monumental upset on American soil, or will Munguia strengthen his credentials as he seeks a world title fight at 168lbs?
Here's everything you need to know ahead of Sunday's fight...
The bout will take place in the early hours of Sunday morning (January 28th).
The main event is scheduled to get underway at around 04:00 on Sunday morning, but that is dependent on the length of the undercard action which is scheduled to commence at 23:00 on Saturday night.
The bout will take place at the Footprint Center in Phoenix, Arizona. The multi-purpose arena opened in 1992 at a cost of $89 million and it is home to NBA side the Phoenix Suns.
The venue has a capacity of over 17,000 and boxing legends Julio Cesar Chavez and Oscar De La Hoya have both fought at the Arizona setting.
Frank Sinatra gave one of his last concerts at the Footprint Center in 1993 and Bon Jovi, Depeche Mode and Fleetwood Mac have all performed at the Phoenix venue.
Munguia v Ryder will be shown live on subscription streaming service DAZN in the UK and Ireland.
The bout will be available in over 200 countries and can be viewed on a myriad of devices.
Munguia is the 10/37 favourite coming into the bout off the cracking contest against Derevyanchenko.
Ryder is a 27/10 chance, but the Gorilla is often underestimated and that hasn’t stopped the Islington fighter pulling off huge wins against Danny Jacobs, Jamie Cox and Zach Parker.
There are no titles up for grabs in this super-middleweight contest, but there is plenty riding on the fight.
Ryder has twice challenged for a world title and the Islington man is currently ranked at number four in ESPN’s 168 pounds list.
Munguia is a former super-welterweight world champion and the unbeaten Mexican will be looking to improve his standing in the super-middleweight division.
There is talk of a contest against Alvarez, should the 27-year-old come through this contest, so there is plenty at stake in Phoenix.
42-0 (33 KOs)
Munguia is unbeaten in 42 contests, with 33 of his 42 victories coming by stoppage. The Mexican is a former super-welterweight champion and the 27-year-old has made the considerable step up to the super-middleweight division.
The Tijuana fighter made his 168 pounds debut against Derevyanchenko, but that opened more questions about Munguia at this weight.
The Ukrainian is a pretty exposed performer, albeit at a high-level, but he was probably just about winning the clash in Ontario, before he was floored by a body shot in the final round.
That swung the contest in Munguia’s favour, but it wasn’t an altogether convincing performance and it will be interesting to see if there is any improvement now that the Mexican has had more time to adapt to competing in the super-middleweight ranks.
32-6 (18 KOs)
Ryder has lost six of his 38 bouts, but those numbers certainly do not do the Islington man justice.
The Gorilla has been beaten by Alvarez, Billy Joe Saunders, Rocky Fielding, Callum Smith, Nick Blackwell and Jack Arnfield.
However, Ryder is a different fighter to the one that lost to Blackwell and Arnfield, and the other four defeats have come against boxers that have all held world titles.
The Londoner took Canelo 12 rounds earlier this year, he was extremely unfortunate not to get the verdict against Smith and there is no doubt that the Briton is a genuine top-level and established super-middleweight performer.
Ryder has only been stopped once in his career and that came way back in 2015 when taking on Blackwell for the British middleweight belt, and the Islington man is one of the toughest and most durable fighters in the super-middleweight division.
