The 21-year-old impressively stepped from prospect to contender last time out, dominating Shakeel Phinn over 10 rounds.

"Many said I was too young to face Phinn, and they'll probably say the same about Falcão, but people need to understand that I don't have time to waste," Mathieu (15-0, 10 KOs) said in a press release.

"I already believe I'm the best in the world, so I have to face the best in the world — and it starts by beating an Olympic medalist in front of my city on June 11."

However, his Brazilian upset-minded opponent has other ideas on how their fight will play out.

"I respect my opponent — I know he's a good, undefeated fighter," said Falcão (32-2, 21 KOs). "But he hasn't faced a boxer like me yet: an experienced fighter who hits hard and has a real hunger to win. I've already fought for a world title and plan to do it again. God will be with me on June 11 — and the victory will go to Brazil."

Mathieu has been a professional for three years and progressed against a steady diet of regional fighters catching the eye and becoming a Ring ambassador. When he stepped up the level of competition, he passed the test in impressive fashion with a win over compatriot Phinn on October 30 in his coming out party.

Meanwhile, Falcão signed with Top Rank on the back of his Olympic success and appeared on the undercard of several big events, running his record to 30-0.

He got a shot at the vacant IBF middleweight title but lost a 12-round unanimous decision to Vincenzo Gualtieri in July 2023 before unbeaten countryman Hebert Conceicao outpointed him over 10 rounds eleven months later. Now though, he's on a two-fight win streak and eager to punch his ticket back into relevancy on the world stage.

The undercard will see a host of fighters return to action against as yet unknown opponents. Big-punching light heavyweight Mehmet Unal (15-0, 13 KOs) will put his regional titles on the line, while 2023 World amateur championship bronze medalist Moreno Fendero (14-0, 10 KOs) does the same at 168 pounds.

Thomas Chabot (12-1, 8 KOs) and Daylen Pepin (2-0) will also see action, as Eye of The Tiger also teased a major addition to the undercard in the coming weeks.
