The former was unsuccessful in his attempt to win the BMF Championship but has been competing in the welterweight division for a while now.Before his controversial loss to 'Gamebred', Nate Diaz was victorious over Anthony Pettis in a three-round fight. While Diaz is no stranger to competing in the lightweight division, he has confirmed that he will be focusing on welterweight moving forward.Meanwhile, Nate Diaz's scheduled opponent Leon Edwards is on the back of a very controversial fight against Belal Muhammad. In a recent five-round main event between the two, 'Rocky' accidentally eye-poked Muhammad, which led to a No Contest.The fight was Edwards's first bout since 2019 but his return didn't turn out the way he expected it to be. That being said though, UFC 262 will mark a quick turnaround for the #3 ranked UFC welterweight, who could guarantee a title shot with a win over Nate Diaz.
