"I have to go back home and look at the fight, see when I made mistakes," Johnson said after the fight, via ESPN. "Adriano is very long, big. It was hard trying to get to him. This is part of the game. You stay in this game long enough, this is bound to happen at some point, right?"

It was the first televised event for the Asian-based mixed martial arts promotion in the U.S.
