Marcio "Ticoto" Barbosa announced himself to the UFC in emphatic fashion, stopping Dennis "The Great" Buzukja by knockout in the first round at UFC Winnipeg on April 18, 2026.
Barbosa, a 28-year-old Brazilian fighting out of Equipe RD Champions, improves to 18-2 with the win and has now extended his winning streak to five consecutive fights. The finishing rate he carries into the promotion is extraordinary — 17 of his 18 career victories have ended before the final bell, with 15 knockouts and 2 submissions, and every single one of those finishes has come in the first round. His output numbers reinforce just how aggressively he operates, with 8.27 significant strikes landed per minute, one of the higher marks you will find anywhere on the roster.
Buzukja, a 28-year-old from the United States training at Longo-Weidman MMA, falls to 12-6 with the defeat. The loss continues a difficult stretch for him — he now holds just one victory in his last five outings. He came in as a volume striker himself, averaging 4.21 significant strikes per minute, but Barbosa's first-round finishing ability proved too much to navigate.
Why it matters
- Barbosa's 17-for-17 first-round finishing record is a genuinely rare career profile and will draw immediate attention at whatever weight class he competes in.
- Buzukja's slide to 1-4 over his last five fights raises serious questions about his UFC future.
- Fellow Brazilian and ranked welterweight Gilbert Burns publicly congratulated Barbosa on the debut, a nod that speaks to the impression the performance left on the broader MMA community.
