Kalyl Silva has knockout power indeed.
Silva, the 22-year-old son of UFC legend Anderson Silva, is going viral this week after his kickboxing debut. Five seconds into the amateur kickboxing bout, Kalyl dodges a leg kick, then delivers a devastating switch kick that knocks his opponent down.
The referee started the count, and the fight is called off roughly 11 seconds into the contest.
Silva, who is also a football player, is now officially 1-0 in his young kickboxing career.
