Marvin Vettori's heading into his fight with Brendan Allen with a heavy heart, but also extra motivation ... the Italian fighter is returning to the Octagon for the first time since the tragic loss of his little bro.
"I'm fighting for my brother," 31-year-old Vettori told TMZ Sports. "For everybody that was very close to him. For my family."
Patrick Vettori tragically died on April 14, 2025, in a house fire in Mezzocorona, Italy .
