Fabricio Werdum wanted Vale Tudo rules for his upcoming bare-knuckle mixed martial arts (MMA) fight against Junior dos Santos. The two former UFC heavyweight champions are set to headline Jorge Masvidal’s upcoming Gamebred Bareknuckle 5 event. While the very concept of bare-knuckle MMA alone might stump some, Werdum wanted to take it a bit farther. Speaking to MMA Junkie , the Brazilian admits he tried to speak to Masvidal about having the fight under Vale Tudo rules to allow soccer kicks, stomps, and more.
