DeBlass announced his retirement from MMA after the bout with Fukuda stating, "After a lot of talk with my family and coaches, I have decided to retire from fighting and focus on my family, my academy and helping my students to achieve their goals.

I have an amazing academy and feel my students need my full attention."
