Silva's father is Anderson Silva, the UFC superstar who owns the record for longest title reign in the MMA promotion's history. The younger Silva, 26, has been in combat sports for a few years himself, and on Saturday he faced Ben Davis in a boxing match.

It wasn't a very long boxing match, however.

With 10 seconds left in the opening round, Silva delivered a left hand that knocked Davis out. The finishing blow came moments after Silva had already knocked his overmatched opponent to the mat.

"I'm not gonna lie, I thought Ben was gonna be a little more prepared but I knew when I looked him in his eyes that he wasn't really there — he was there but he really wasn't there," Silva said immediately after the fight.

"He's strong and he could punch, but I was like, 'you know what? Let me just let this experience do the talking and just take it play by play.'"
