One week after George Kambosos scored a shocking upset of Teofimo Lopez to win three of the four recognized lightweight world championships, Devin Haney is set to defend the fourth belt against dangerous for and former world champion Joseph Diaz Jr. It's a dangerous fight for 23-year-old Haney and one that could see the division thrown into further chaos.

Haney (26-0, 15 KO) has been outstanding as a professional but his style and skills have made it hard for him to find appropriate opponents in a division loaded with talent. In his most recent outing, Haney was hurt badly late in his most recent fight, getting caught by Jorge Linares. He still managed to survive to the final bell and retained his title in the process. Needing a big opponent, Haney began calling out Diaz when Diaz's fight with Ryan Garcia fell apart due to a Garcia hand injury.

Diaz (32-1-1, 15 KO) is a former IBF super featherweight champion. His lone career defeat came in 2018 when he dropped a decision to Gary Russell Jr. in a fight for the WBC featherweight title. Since that loss, Diaz has gone 6-0-1, including defeating Javier Fortuna in his most recent outing, picking up the WBC interim lightweight title in the process.

This card also marks the return of undisputed women's welterweight champion Jessica McCaskill. The 37-year-old Missouri native is looking to continue her impressive run when she takes on late replacement Kandi Wyatt. McCaskill was expected to take on Victoria Bustos in this spot, but Bustos had issues getting her visa to the U.S. and was forced to withdraw. McCaskill achieved undisputed status when she stunned then champ Cecila Braekus in 2020 by majority decision then beat her by unanimous decision in the 2021 rematch.

Plus, super lightweight Montana Love looks to cap off a tremendous 2021 when he takes on Carlos Diaz. Love is 2-0 with a pair of stoppages so far this year, including an impressive win over former champion Ivan Baranchyk in August. Another win on Saturday could move him closer to a potential title opportunity, especially over someone like Diaz. The Mexican enters with a 29-1 record and 14 knockouts on his resume. He's won three in a row since his lone pro defeat at the hands of Jose Zepeda.
