Jafel Filho made sure to not go to the judges in his Dana White Contender Series debut. The Brazilian flyweight prospect put away Roybert Echeverria in the opening bout of Dana White Contender Series 55 . Filho (14-2) had a competitive fight with Echeverria (7-1), but a clean left hook in the third round closed the show and kept it from going to the scorecards. Dana White Contender Series 55 took place on Tuesday at the UFC Apex in Las Vegas
