#2. Nick Diaz vs. Matt Brown
At the age of 40, Matt Brown is even older than Nick Diaz. Many began to call for Brown to hang up the gloves following his loss to Carlos Condit in early 2021. Then, Brown came out and knocked Dhiego Lima unconscious in only two rounds at UFC Vegas 29.
The KO highlight had great traction on social media, demonstrating the huge fan base 'The Immortal' still retains 13 years after his UFC debut.

Considering his age, 2022 might be Brown's last year competing in MMA and a retirement fight against Nick Diaz would be the perfect way to call it a day.
#1. Nick Diaz vs. Donald Cerrone
Donald 'Cowboy' Cerrone may be entering the twilight of his career, but he remains an iconic figure in the world of MMA. An impressive 36-16 record contains impressive wins over Eddie Alvarez, Alexander Hernandez and Al Iaquinta.
Cerrone's durability isn't what it once was, but his skill set remains just as sharp. Cerrone previously competed against Nate Diaz, drawing out a competitive third-round war from the younger Diaz brother.
Nick Diaz's slick boxing would clash against Donald Cerrone's clinical Muay Thai in what would be a true veteran fight. There is also the added caveat that Cerrone is not adverse to the odd takedown and has some solid Brazilian jiu-jitsu of his own.
