Raymond “Danger” Muratalla (24-0, 17 KOs) will make the second defense of his IBF Lightweight World Championship against Brazilian former world champion Robson “O Brabo” Conceição (21-3-1, 10 KOs).
Muratalla-Conceição will serve as the co-feature to the Lamont Roach Jr.- William Zepeda card on Saturday, Aug. 1, at The Theater at Virgin Hotels Las Vegas.
Headlining the TNT Sports and DAZN’s “The Fight,” a new monthly live boxing series, Roach Jr. (25-1-3, 10 KOs) of Washington D.C. and Zepeda (33-1, 27 KOs) will battle for the vacant WBC Lightweight World Championship.
“After my last fight, the boxing world really got to know who I am,” said Muratalla. “People saw me as the underdog, even though I was the champion, and I showed that I can’t be underestimated. Now I’m defending my title against another Olympic gold medalist, and I plan to look even better. I’m focused, I’m ready, and I’m handling business on August 1.”
“They said it was impossible when I dreamed of winning an Olympic gold medal,” said Conceição. “They said that when I pursued my first world title. I accomplished both, and it’s no different now. I have a lot of respect for Raymond Muratalla, but I’m ready for this challenge. I want to prove that determination, experience, and the heart of a champion can overcome any obstacle. On August 1, I will fight for myself, for my family, and for all of Brazil.”
Muratalla, from Fontana, California, debuted as a pro in 2016 and steadily rose through the lightweight ranks. His standout performances include second-round stoppages of big-punching Jeremia Nakathila in May 2023 and Jesus Perez in November 2024. In May 2025, Muratalla defeated Zaur Abdullaev to become the interim IBF lightweight world champion. He was elevated to full champion the following month after Vasiliy Lomachenko announced his retirement. In February, he outpointed Olympic gold medalist Andy Cruz to retain his crown in his best performance to date.
Conceição, Brazil’s first Olympic boxing gold medalist, repeatedly challenged the sport’s elite before winning a world title on his fourth attempt. After setbacks to Oscar Valdez and Shakur Stevenson, he battled Emanuel Navarrete to a majority draw in November 2023 before edging O’Shaquie Foster to capture the WBC junior lightweight world title in July 2024. Conceição lost the belt to Foster in their rematch that November, but has since scored two victories at home.
Additional information on the undercard will be announced in the coming weeks.
