IBF super featherweight champion Eduardo ‘Sugar’ Nunez faces long-reigning WBO ruler and compatriot Emanuel Navarrete in an all-Mexican world title showdown on Saturday in Glendale, Arizona.

Given the promotional tagline of ‘The Next King of Mexixo’, the bout will indeed crown a new fighting hero for a boxing-mad nation.

Navarrete (39-2-1, 32 KOs) is probably already assured of that status as a three-weight world champion who has reigned at 130 pounds since February 2023, when he recovered from a heavy fourth-round knockdown to stop Australia’s Liam Wilson in the ninth.

The 31-year-old’s progress hasn’t been without bumps in the road since then. Navarrete boxed to a 12-round draw against Robson Conceicao in November 2023 despite dropping Brazil’s 2016 Olympic gold medalist twice. That was followed by an unsuccessful move up to lightweight and a loss to Denys Berinchyk with the vacant WBO belt on the line.

After battering Oscar Valdez in a one-sided December 2024 rematch, Navarrete held onto his title last May in controversial fashion against Charley Suarez. Their fight was initially stopped and awarded to Navarrete on a technical decision, the referee ruling that a cut over his left eye had been caused by a headbutt. However, replays clearly showed a Suarez punch had caused the injury and the verdict was changed to a no-contest.

Nunez (29-1, 27 KOs) has not experienced any such turbulence and is on a 19-fight winning streak. It is notable that his two world title fights against Masanori Rikiishi and Christopher Diaz-Velez are the only times the 28-year-old has been forced to go to the scorecards, meaning there are still questions to be answered regarding his much-vaunted power at world level.

Emanuel Navarrete vs. Eduardo ‘Sugar’ Nunez undercard 

Here’s a breakdown of all the main card action on the Nunez vs. Navarrete bill:

Tahmir Smalls vs. Abel RamosDivision/Weight: WelterweightSmalls record: 16-0Ramos record: 28-6-3Belts at stake: N/A

Rising star Smalls gets a step up in class and a chance to position himself in a wide-open 147-pound division.

Ramos has not fought since boxing to a draw against the now dethroned WBC champion Mario Barrios in December 2024.

Emiliano Vargas vs Agustin QuintanaDivision/Weight: Super lightweightVargas record: 16-0Quintana record: 22-2-1Belts at stake: NABF Junior, WBO Latino

Vargas is one of the most highly touted prospects in the sport and is staying busy after going 4-0 in 2025.

Three of those wins came via stoppage and Argentina’s Quintana, on a four-fight run of points victories since his 2022 KO loss to Juan Javier Carrasco, will hope to take Vargas into deeper waters.

Arturo Cardenas vs. Jordan MartinezDivision/Weight: Super bantamweightCardenas record: 17-0-1Martinez record: 16-0Belts at stake: WBC Continental Americas

Undefeated records are on the line when Cardenas puts his regional strap on the table.

The Mexican has mixed in better company but only has nine stoppages to his name. Arizona’s own Martinez will hope to make his power tell, with all but one of his victories having come via the power punch.

Trini Ochoa vs. Oscar Alvarez JrDivision/Weight: Super lightweightOchoa record: 21-0Guerrero record: 14-2Belts at stake: N/A

Another Arizonan on the card is Ochoa, who was pushed close last time out, hanging on to his undefeated record with a 10-round split decision win over Francisco Cuadrado in Phoenix.

Alvarez is on a five-bout run of knockout wins, having claimed 12 of his 14 career victories inside this distance. This could be one of several barnburners on the card.
