Robson Conceição (37) faced unbeaten IBF lightweight champion Raymond Muratalla (29) on 1 August 2026 at The Theater at Virgin Hotels in Las Vegas. The bout, previously billed as a co‑main event of a lightweight double‑header and streamed on DAZN, TNT and Canal Combate, ended in a unanimous decision for Muratalla (118‑110, 119‑109, 119‑109). Conceição, the 2016 Olympic gold‑medalist, was out‑boxed and failed to disrupt Muratalla’s jab and body work, missing the chance to become a two‑division world champion alongside Brazilian legends Eder Jofre and Acelino “Popó” Freitas. After the win, Muratalla said making the 135‑lb limit was becoming difficult and hinted at moving up to the 140‑lb junior‑welterweight division. The result leaves Muratalla unbeaten at 25‑0 with 17 knockouts and retains his IBF lightweight crown.
