5. B.J Penn
Penn was a massive star in the UFC as a two-weight champion before his downward spiral. In 2019, he was involved in several street brawls. He fought one man outside The Lava Shack in Hawaii’s Big Island. Allegedly, he gave the man a single free shot to punch him in the face. Unfortunately, his adversary knocked Penn unconscious with a single blow.

However, that wasn’t the end of their confrontation. ‘The Prodigy’ returned to punish his opponent. He took him down to the ground and unleashed a pounding on the fellow. Never in his life did he think he would go head-to-head with a former UFC champion. It definitely wasn’t an ideal situation. The UFC cut Penn after this because it wasn’t his first crazy incident and he lost a lot of fights.
