After the fight, Buckley stated that UFC president Dana White had already informed him that he would be receiving all of his bonuses.“The boss just told me that he wants to give me all of the bonuses, so I’m welcome to it, I want all of it," Buckley said, per talkSPORT."To be honest with you, it’s surreal; a cloud came over my head when he was talking to me, so I couldn’t hear nothing, but once that money came in, once he talked about that, then it cleared up a little bit. But it’s awesome, it’s surreal that Dana White came over and talked to me.“It was just open. I seen that he still had my legs, I was still able to balance with him grabbing my foot, so I just spun and kicked. I aimed and I fire and it got the result we needed.

"I know I landed flush, I didn’t know if I knocked him out though until he locked up and I said it was game over. I train it all the time, the only thing that was different was him holding my leg, but I practice it all the time.

“It’s been cool, the first two, three days were cool, but then after a while, just being trapped and isolated, I was ready to fight. But it’s a beautiful place; they welcomed us with great warmth, just kept us safe and kept us pleased, so it was wonderful.”
