Zabit Makhachev has withdrawn from his scheduled grappling match against Raul Rosas Jr. due to a health issue. His brother Khassan Makhachev will step in as a replacement.
Raul Rosas Jr. will face a last-minute replacement opponent after Zabit Makhachev withdrew from their scheduled ACB Jiu-Jitsu grappling match due to a health issue. Khassan Makhachev, Zabit's brother, has been named as the substitute ahead of the contest.
Rosas Jr., known by his nickname "El Nino Problema," is just 21 years old and already carries a professional MMA record of 12-1-0. The American fighter, who trains out of 10th Planet Jiu-Jitsu Las Vegas, brings genuine submission pedigree into this grappling format, averaging 1.1 submission attempts per 15 minutes in MMA competition alongside a takedown rate of 4.01 per 15 minutes. At five-foot-nine with a 67-inch reach, he is a physically compact but technically sharp competitor who operates out of a switch stance.
No verified data for Khassan Makhachev is available in the AgentMMA database, though he steps in as a replacement connected to the Makhachev family, which carries its own name recognition in grappling and combat sports circles.
Why it matters
- The late withdrawal shifts the matchup entirely, replacing a confirmed name with an unknown quantity for Rosas Jr.
- A grappling-only format puts Rosas Jr.'s 10th Planet submission game directly on display, removed from the striking elements of his MMA record.
- At only 21 with a 12-1 MMA record, Rosas Jr. is still building his profile, and a high-profile grappling appearance carries real visibility stakes regardless of opponent.
