The son of UFC legend Anderson Silva won his boxing debut in Brazil with an impressive fourth-round knockout.
Kalyl, 23, stopped his opponent Paulo dos Santos by landing a brutal left hook to the body followed by an overhand right which left him in a world of pain on the canvas. Dos Santos went down holding his stomach after the body shot and was unable to beat the referee's count, awarding Kalyl his first professional win in the ring.
"Pro debut started off with a bang! Fourth round knockout," he wrote. "Thank you to everyone that’s part of this journey with me. Forever thankful. On to the next." It was Kalyl's first fight since he lost a decision to Michael Mitchell in an amateur kickboxing bout that took place in September.
