Raymond Muratalla Next IBF Defense Announced

IBF Lightweight World Champion Raymond Muratalla  will make the second defense of his title against former world champion Robson Conceição of Brazil, as Top Rank Boxing and Golden Boy Promotions confirmed Monday afternoon.

The Muratalla-Conceição clash will serve as the co-main event on Saturday, August 1, at The Theater at Virgin Hotels Las Vegas, alongside the highly anticipated lightweight title showdown between Lamont Roach Jr. and William Zepeda. The event is presented by Top Rank Boxing, Golden Boy Promotions and TGB Promotions.

Fresh off a career-defining, decision victory over Olympic Gold Medalist Andy Cruz, Muratalla, (24-0, 17 KOs), is eager to continue proving himself among boxing’s elite.

“After my last fight, the boxing world really got to know who I am,” Muratalla said in the release. “Even as the champion, many viewed me as the underdog, but I showed that I belong at the top level. Now I’m facing another Olympic gold medalist, and I plan to deliver an even better performance. I’m focused, prepared, and ready to take care of business on August 1.”

Conceição, (21-3-1, 10 KOs) is Brazil’s first Olympic boxing Gold Medalist, and a former 130 lb. world champion. He enters the bout determined to add another chapter to his accomplished career.

“They said it was impossible when I dreamed of winning Olympic gold,” Conceição said Monday. “They said the same when I pursued my first world title. I achieved both goals, and this challenge is no different. I respect Raymond Muratalla, but I believe my experience, determination, and championship mentality will carry me through. On August 1, I’ll be fighting for myself, my family, and all of Brazil.”

Headlining the card, Lamont Roach (25-1-3, 10 KOs) battles Mexican knockout artist and top lightweight contender William Zepeda (33-1, 27 KOs) for the vacant WBC lightweight world championship. The event will air live in the United States on TNT Sports and truTV and steram globally on DAZN. 

A native of Fontana, California, Muratalla turned pro in 2016 and has steadily climbed the lightweight ranks with notable victories over Jeremia Nakathila and Jesus Perez. He captured the interim IBF lightweight title with a victory over Zaur Abdullaev in May 2025 and was elevated to full champion following future hall of famer Vasiliy Lomachenko’s then retirement. Muratalla most recently retained his title with a unanimous decision victory over Cruz in what many consider the best performance of his career.

Conceição has long competed against the sport’s elite. Following championship opportunities against Oscar Valdez and Shakur Stevenson, he fought Emanuel Navarrete to a majority draw before defeating O’Shaquie Foster to capture the WBC junior lightweight title in July 2024. However, he lost the belt in a rematch with Foster later that year,

Still, Conceição has rebounded with two consecutive victories and now seeks to become a two-division world champion.
