#2. Former UFC title challenger Colby Covington
Colby Covington hasn't been linked to any upcoming UFC events. He is coming off a decisive win over former teammate Jorge Masvidal in March. Despite the win, the rivalry wasn't over as the two were involved in an altercation outside a restaurant in Miami, Florida.
The promotion could possibly book him to fight Diaz because of the buildup. Covington is someone that doesn't shy away from trash talk, which could lead to entertaining press conferences. With Diaz being a fan favorite and 'Chaos' usually booed by fans, it could lead to a lively atmosphere.

Both fighters are known for their durability, which could make a potential bout intriguing. Obviously, Covington would attempt the takedowns, but Diaz could be capable of submitting him should he find an opening on the ground.
#1. No.3-ranked UFC welterweight Khamzat Chimaev
Khamzat Chimaev has quickly ascended the UFC welterweight rankings. In less than two years in the promotion, he is already the No.3-ranked welterweight. What makes this ascension even more impressive is that he has fought at both welterweight and middleweight.
'Borz' proved he is a legitimate welterweight contender by defeating former title challenger Gilbert Burns. His durability was on full display as he managed to withstand 'Durinho's power.
Dana White even mentioned that he was interested in booking the Diaz fight:
"That's a fun fight, Khamzat is ranked number three in the world, him and Diaz would be fun."
Chimaev could gain a lot should he defeat Diaz as it would be another accomplished fighter on his resume. Perhaps Diaz could be more open to the fight now that 'Borz' is a bigger name in the sport.
