- Attendance was 3,705.
Both men landed some decent shots in the opening round as Abril moved around and looked to work with straight shots from a distance. Rios came forward and threw combinations on the inside. Abril was warned for using his forearm in a clinch. Abril was again warned in Round 2 for using his forearm in a clinch as he tried to tie up Rios when in close. Rios likely earned the round landing cleaner power punches. Rios snapped back the head of Abril in Round 3 with an uppercut and seemed to take the round with aggression. Abril found success with the jab and straight right hands in Round 4. Rios was warned in Round 4 for a kidney punch.
