The lightweight bout will take place at BleauLive Theater at Fontainebleau in Las Vegas and serve as chief support for the heavyweight clash between Jarrell Miller and Lenier Pero on DAZN.

Chaves (21-0, 18 KOs), a 25-year-old from Buenos Aires, will be making his United States debut. Chaves sports an 85% knockout ratio and is ranked No. 2 by the WBO, No. 6 by the IBF and No. 13 for the WBC at 135 pounds.

The hard-hitting southpaw’s last four fights have all been stoppages and lasted a total of nine rounds.

Madueno (31-4, 28 KOs), a 27-year-old from Mexico, is also a power puncher but has lost three out of his last four fights, including back-to-back defeats against Keyshawn Davis in July 2024 and Oscar Duarte in February 2025.

“Signing with Matchroom is a crucial step in my professional career,” Chaves said in a statement. “I’m highly motivated and eager to make a name for myself in the world of boxing. I’m very grateful to be part of the world’s number one promotional company.

“It’s going to be a tough fight. Madueno is a very experienced and dangerous opponent who has fought against some big-name boxers. I’m in the best shape of my life, both physically and mentally. As always, I’ll give it my all in the ring, and I have no doubt that I’ll come away with the victory.”
