The card is headlined by unbeaten, two-time Super Middleweight World Champion David “El Bandera Roja” Benavídez against top contender Kyrone “Shut It Down” Davis, live on SHOWTIME CHAMPIONSHIP BOXING in a telecast that begins at 9 p.m. ET/6 p.m. PT.

Fighting out of Los Angeles, California, the 29-year-old Myrthil (17-0, 13 KOs) discovered boxing at age 18, after his family relocated from Haiti to the United States. Following a stellar amateur career, Myrthil made his pro debut in January 2017 with a second-round TKO over Allan Varela in Tijuana, Mexico. In September 2019, he won an eight-round unanimous decision over Jonathan Steele in Las Vegas. The performance caught the eye of Floyd Mayweather, who sat ringside for that bout and ultimately signed Myrthil to his Mayweather Promotions outfit. Most recently, Myrthil outpointed Johnny Rodriguez over eight rounds in February 2020.

Originally from Memphis, Miller (21-2, 6 KOs) now resides in Las Vegas and also fights out of the Mayweather Promotions stable. The 28-year-old veteran’s list of accomplishments includes wins over former champions Jamel Herring and Jezreel Corrales. Miller will look to get back on track after his 12-fight win streak was snapped in his most recent bout, a points loss to unbeaten contender Michel Rivera in October 2020.

Non-televised undercard action will also feature undefeated, 18-year-old prospect Elijah Garcia (8-0, 7 KOs) taking on Todd Manuel (20-18-1, 6 KOs) in six-rounds of super welterweight action, Guadalajara, Mexico’s Jonathan Fierro (11-0, 10 KOs) in an eight-round super featherweight bout, Arizona native Jesus Ibarra (11-0, 5 KOs) facing Hector Suarez (12-13-2, 6 KOs) in a six-round super lightweight clash, former amateur standout Micky Scala (2-0, 1 KO) versus Martez Jackson (5-5-3, 2 KOs) in a four-round super welterweight match, Congo’s Farid Ngoga (4-0, 4 KOs) taking on Isaac Freeman (3-9-2, 3 KOs) in a four-round super welterweight duel, and Phoenix resident Keenan Carbajal (22-2-1, 14 KOs) in an eight-round featherweight fight.
