Demetrious Johnson was tired of dealing with all the behind-the-scenes politics of MMA.
In September, ‘Mighty Mouse’ announced to the world that he was officially retiring from the sport of mixed martial arts after nearly two decades of dominance. Along the way, Johnson became the UFC’s first-ever flyweight champion and defended the title an incredible 11 times, the most consecutive title defenses in promotional history.
After being traded to ONE Championship, a first in the sport of MMA, Johnson picked up right where he left off, winning the ONE Flyweight World Grand Prix tournament en route to capturing the ONE flyweight MMA championship via a spectacular flying-knee knockout of Adriano Moraes.
