The 35-year-old Ugás (26-4, 12 KOs) has established himself as an elite welterweight since returning from a layoff in 2016, and was elevated to world champion in January after winning a WBA belt by defeating Abel Ramos last September. Ugás, who is from Santiago, Cuba and now lives in Miami, Florida, was on an eight-fight winning streak before losing a narrow split-decision to Shawn Porter in a world title fight in March 2019. The Olympic bronze medalist trains in Las Vegas and owns victories over then undefeated fighters Jamal James, Omar Figueroa Jr. and Bryant Perrella, plus veteran contenders Thomas Dulorme and Ray Robinson.

Born in Santa Fe, Argentina, Maidana (18-1, 13 KOs) will look to follow in the footsteps of his older brother, former two division champion Marcos Maidana, and become the latest Argentine world champion on August 21. The 29-year-old was unbeaten in his first 16 pro fights, capping off that run with a knockout of Andrey Klimov in July 2018. Since dropping a January 2019 decision to Jaider Parra, Maidana has bounced back with a knockout of Ramses Agaton in September 2019 and a 10-round decision victory over Carlos Cordoba in April of this year.

Guerrero (36-6-1, 20 KOs) is a three-time world champion who has won world titles at featherweight and super featherweight, and has fought a stacked lineup of elite fighters, including Floyd Mayweather, during a superb career. The Gilroy, California native returned from a 2017 defeat to Omar Figueroa Jr. to win his last three contests. After stopping Adam Mates in December 2018 and Hevinson Herrera in March 2019, Guerrero most recently won a unanimous decision over Gerald Thomas in September 2019.

Ortiz (32-6-3, 25 KOs), a former 147-pound champion, will return to the ring for the first time since a February 2018 draw against two-division champion Devon Alexander. The 34-year-old native of Garden City, Kansas, who now lives in Ventura, California, has faced some of the top names in the 147-pound division during his career. Ortiz won the welterweight title with a unanimous decision victory over Andre Berto in April 2011, before losing the title to Floyd Mayweather.

The Filipino sensation Magsayo (22-0, 15 KOs) fights out of Pasig City, Metro Manila and most recently knocked out Pablo Cruz in four rounds in April 2021, following his U.S. televised debut in October 2020 that saw him defeat Rigoberto Hermosillo on FS1. The 26-year-old fights in the U.S. for the fifth time overall on August 21 and against his toughest competition to date in the former champion Ceja. Magsayo owns 12-round decision victories over Shoto Hayashi and Jose Robles Olvera, and a sixth-round stoppage of former title challenger Chris Avalos.

A former super bantamweight champion, Ceja (32-4-1, 28 KOs) will move up to featherweight as he seeks an opportunity to capture a championship in a second division. Ceja's 2019 saw him engage in two action-packed battles, dropping a June contest to former champion Guillermo Rigondeaux and most recently fighting unbeaten super bantamweight champion Brandon Figueroa to a draw in November. The 28-year-old captured his 122-pound title with a stoppage of Hugo Ruiz in 2015, and has also challenged for a bantamweight title throughout his career.
