Aztec Duel

Two Mexicans with previous history touch gloves in the Octagon. Fabián Quintanar had refused, more than once, to fight against "Pato" Martínez, but this time nothing will stop the fight. The first challenge of the season tests the athletes' skills in unknown territory, and punishment for losers intensifies rivalry. The Quarterfinal match-ups are announced and one fighter is given a second chance in the competition.
