Mazzulla is in attendance for UFC 303 at T-Mobile Arena in Las Vegas as part of International Fight Week. Mazzulla, who actively trains in jiu-jitsu, checked in on UFC’s social media channels.

Mazzulla previously attended UFC 292 in Boston last August to support his friend Zhang Weili on that card at TD Garden. Throughout the Celtics’ path to winning the 2024 NBA Finals, their head coach often motivated his team and utilized UFC examples in his teachings during the run.
