Tsarukyan revealed Dariush’s mistake that led to the knockout

“We have practiced this a lot. I wanted to show a knee strike and then throw a hook. Usually when you grab your opponent, he drops his hands. That's how Oliveira knocked him out - he hit a deuce and then hit a kick. I wanted to grab him, pull his arms down, and then hit him with a hook. But the knee also plays a role. You need to change attack levels,” Tsarukyan said in an interview with ESPN.
