In the main event, IBF light heavyweight world champion Artur Beterbiev (13-0, 13 KOs) –  the only current world champion in boxing with a 100 percent knockout ratio –  will fight the hard-hitting Radivoje "Hot Rod" Kalajdzic (24-1, 17 KOs). And, in the co-feature, Jerwin "Pretty Boy" Ancajas (30-1-2, 20 KOs) will make the seventh defense of his IBF junior bantamweight world title against No. 1. contender Ryuichi Funai (31-7, 22 KOs).

Flores, a one-time standout amateur who signed with Top Rank in 2016 at the age of 16, is now one of the sport's top young ticket-sellers. This is what he had to say.
