Raymond Muratalla Defeats Robson Conceição to Retain IBF Lightweight Title

Raymond Muratalla Robson Conceição IBF lightweight title Las Vegas weight class change

American IBF lightweight champion Raymond “Danger” Muratalla (29, 25‑0, 17 KOs) successfully defended his world title on 1 August 2026 in Las Vegas, Nevada. The bout, held at The Theater at Virgin Hotels, ended with a unanimous decision in Muratalla’s favor, the judges scoring the 12‑round fight 118‑110, 119‑109 and 119‑109.

Brazilian challenger Robson Conceição, 37, a 2016 Olympic gold‑medalist and former super‑featherweight world champion, sought a second world title that would place him alongside Eder Jofre and Acelino “Popó” Freitas as the only Brazilians with championships in two weight classes. Despite his experience, Conceição was out‑boxed throughout, unable to disrupt Muratalla’s jab and body work. The fight was broadcast live on DAZN, TNT and Brazil’s Combate channel.

After the victory, Muratalla said making the 135‑lb lightweight limit had become difficult and hinted he may move up to 140 lb, stating, “I think making 135 is a little hard for me. I’m going to feel a lot better at 140.” The comments suggest a potential future shift to the junior‑welterweight division.
