Wallisson Oliveira Enters Medium Heavy at the 2026 Nashville Fall Open: Two Finals for the 2024 No-Gi World Champion
The 2024 No-Gi world champion has one opponent in each tournament in Franklin: last year’s gi champion Jonathan Carvalho, and Clay Mayfield in no-gi.
Wallisson Oliveira is registered at medium heavy in both tournaments at the Nashville Fall International Open, October 24 and 25 at the Williamson County Ag Expo Park in Franklin, Tennessee. Each division has two entrants, so each of his matches is a final.
Wallisson won the No-Gi Worlds at medium heavy in 2024 and the Pan No-Gi at heavy earlier this month. He’s No. 9 in the no-gi ranking as of October 22. No stream has been announced.
