31-year-old Gutierrez, who came into UFC 281 as an unranked fighter, knocked out number 12 ranked bantamweight, 41-year-old Edgar, about halfway through the first round of their contest with a perfectly placed knee. It was the last fight of Frankie's Hall of Fame career.

"It's definitely bittersweet. I knew I still had a job to do, but at the end of the day, I didn't enjoy ... It was bittersweet. I gotta do what I gotta do and I won the fight but no one really likes to see a champion go down like that. It hurt me a bit. It did."

Chris says Edgar was someone he looked up to as a young MMA fan ... and the former champ actually inspired him.

"The reality is it was an honor to share the cage with him, an honor to share the Octagon. He's someone that I grew up watching from the beginning. He was the little engine that could. A smaller guy taking on these giants and he would come out on top. He would find a way. He inspired me as a kid to kind of push through life."

With the win over Edgar, Gutierrez cracked the top 15 ... and now sits in the 13th position. Chris is in the midst of a 4 fight win streak ... and hasn't lost since 2018 (he fought to a draw in August 2020).

We asked Gutierrez who he wants next ... and he had some ideas.

"I already have three people on my mind. Pedro Munhoz, Dominick Cruz, or Rob Font would be some good ones," Chris says.

But, no matter what happens from here ... Chris is grateful for all his success.

"To be honest I never envisioned myself being where I'm at in life so every day is like a blessing."

As for Frankie ... he goes down as one of the greatest fighters in UFC history.
