Jorge Masvidal appears confident and relaxed for his test against Nate Diaz

Jorge Masvidal does not flinch at the prospects of fighting Nate Diaz in a boxing match. Masvidal has been there before, and beaten Diaz, when the pair starred at UFC 244 on Nov. 2, 2019. Since then, both 39-year-olds have spewed a healthy dose of venom at one another, highlighted last month by a brawl between the two camps during the last press conference trying to build the fight.

This Saturday at the Honda Center in Anaheim, California, Diaz and Masvidal, two past-their-prime MMA stars, will fight in a 10-round light heavyweight.
