After KOing the Brazilian, the former UFC star hit a devastating soccer kick
Many fight fans were stunned by the legal strike
Abe ended De Souza's lights with a stunning one-two in round two of their showdown at Japan's Saitama Super Arena.
After the right hand was connected, De Souza crumpled to canvas and laid flat on his stomach unconscious.
Abe continued his assault on De Souza, landing a devastating soccer kick right at him.
Fighting fans were not happy about the sickening academic strike.
One tweet: "Soccer kick uncalled for." Guy should be ashamed
Another commented: "I like soccer kicks, but I don't know when the dude is f *****g."
Another said, "Unfortunately, this is legal."
In most MMA promotions around the globe, including the UFC which has adopted the unified rules for the sport, soccer kicks are prohibited.
However, sickening strikes and knees to the head are allowed in Asian-based fight promotions ONE Championship or RIZIN.
However, many fans have demanded that strikes be allowed in all promotions.
One fan stated, "Best rule in MMA."
Another stated that MMA requires soccer kicks and knees in order to bring down an opponent. The Unified MMA Rules are garbage.
The 30-year-old Abe won over De Souza and moved to 5-1 in six of his previous outings.
