Otto Wallin Signs With Zuffa Boxing

By Per-Åke Persson

Houston, Texas, based Swedish heavyweight Otto Wallin (28-3-0-1) has announced on social media and in an interview with Expressen back home that he has signed with Zuffa Boxing.

No details are made public but Wallin says he is guaranteed three fights a year and Otto also admits that he has been in a tough spot without a big promoter backing him up.

The now 35-year old moved to Houston last year and is now trained by Ronnie Shields after previously being trained by Joey Gamache since turning pro in 2013.

Wallin broke up with Gamache after the loss to Dereck Chisora in 2025 and has fought once since then knocking out an overweight opponent in Chris Thomas.
