On Saturday night from the MGM National Harbor in Maryland, the co-main event featured former world champions Javier "El Abejón" Fortuna (35-2-1, 24 KOs) from the Dominican Republic knocking out Argentina's Jesús Andrés Cuellar (29-4, 22 KOs) at the 2:01 mark of the second round in their super featherweight showdown.

Fortuna knocked down Cuellar in both the first and second stanzas. Shortly following the second knockdown, the referee had seen enough, calling a stop to the action.

"I expected a tough fight," said Fortuna. "I wanted to be very active in this fight and win it for the Republic!

"This being a WBC eliminator bout, we expect a shot at (Devin) Haney next," concluded Fortuna.

In the main event of the card,  undefeated former champion Brian Carlos Castaño (16-0-1, 12 KOs) of Argentina scored a technical knockout win over veteran contender Wale "Lucky Boy" Omotoso (28-5, 22 KOs) of Nigeria in a super welterweight showdown. The official time of the stoppage came at the 3:00 mark of round five.

Sensational Cuban prospect David Morrell Jr. (2-0, 2 KOs) scored a quick knockdown against North Carolina's Quinton Rankin (15-7-2, 12 KOs) in the first frame, another knockdown in the second round, with the contest being waved off at the 1:01 mark of round two in their light heavyweight contest.

The opening bout on FS1 saw welterweight Ryan "Cowboy" Karl (18-2, 12 KOs) of Texas get dropped in the first round before fighting his way to a stoppage victory over Costa Rica's Berman Aguilar (15-6-1, 5 KOs) at the 3:00 mark of round five. Aguilar was unable to answer the bell to start round six due to an injured hand.
