Tsarukyan on Oliveira's 'guillotine': 'I couldn't give up'

Recall, Tsarukyan won by split decision of the judges, but was close to defeat with a choke prelim at the beginning of the fight.

"It was a very tight choke. But I knew I was going to get out of it and win the fight. Because I believed in myself, I knew I couldn't tap and give up. I've worked so hard - how can I give up now? I had a lot of thoughts in my head, but I knew how to get out of this position. And I did. But the choke was very tough," Tsarukyan told ESPN MMA.
