The UFC fighter recently had a sparring session with professional boxing great and Youtube celebrity Logan Paul at the UFC Performance Institute. The sparring session may not have gone the way that Paul wanted, as Costa knocked him out with a right.
Paul posted the knockout on Youtube, while ESPN MMA also posted their own version on Twitter:
While Paul did get his clocked cleaned by Costa during the sparring session, one thing the Youtube celebrity did do better as was with the grappling exchanges against Costa. Paul has hinted at transitioning to professional MMA in the past, but he should probably learn some striking defense before stepping up to the big leagues.
