Juliano Machado vs Willian Masuda

At 2026 Londrina No-Gi Jiu-Jitsu Championship, Juliano Machado and William 'Kabuto' Massuda met in a no-gi match in Londrina, Brazil. During the match, Machado lifted Massuda and, with Massuda inverted, dropped his full body weight onto Massuda's head and neck in a slam, a move prohibited under federation rules. The referee stopped the bout immediately.

Massuda was unable to stand following the incident. He was later hospitalized and underwent spinal surgery.
