How did Yair Rodriguez come up with the elbow?

Yair Rodriguez joined Ariel Helwani of ESPN just two days after the show to provide an update on his health status and share details of how everything transpired. Rodriguez accepted that while nobody had specifically taught him to throw back elbows, he picked it up from Donald Cerrone, who he was training with for the fight.

Of the last-second knockout at UFC Denver, Yair Rodriguez told Ariel Helwani:

"Nobody taught me [how to throw that elbow]. It was something I saw Cowboy doing in the back [while warming up] and I started practicing it."

Accusing 'The Korean Zombie' of letting his guard down at the end, Rodriguez further said:

"The last second was perfect. The momentum, everything was perfect. I made him react as I wanted him to react the whole fight like that. Sometimes when I wanted him to react that way, he was too aggressive that I couldn't counter. Whenever you think everything is over, that's when you put your hands down and it's what happened."
