A jam-packed lineup featuring a former title challenger and U.S. Olympian, a top prospect in his toughest test to date and an emerging unbeaten super lightweight will highlight the Showtime Boxing Countdown live streaming presentation this Saturday, March 4 in a Premier Boxing Champions event from Toyota Arena in Ontario, Calif.

Super welterweight contender Terrell Gausha will top the action in a 10-round showdown against once-beaten Brandyn Lynch that streams live on the Showtime Sports YouTube channel and SHOWTIME Boxing Facebook page. The lineup kicks off at 6:30 p.m. ET/3:30 p.m. PT and is hosted by award-winning MORNING KOMBAT live digital talk show hosts Luke Thomas and Brian Campbell.

Also featured in the ring will be sensational rising prospect Travon Marshall stepping up in competition to face the veteran Justin DeLoach Dock in an eight-round welterweight clash, plus unbeaten super lightweight Enriko Gogokhia duels Samuel Teah in the 8/10-round opener.

The live streaming fights will precede the Showtime Championship Boxing telecast at 9 p.m. ET/6 p.m. PT headlined by all-action former world champions Brandon “The Heartbreaker” Figueroa and Mark “Magnifico” Magsayo meeting for the vacant Interim WBC Featherweight Title.

A member of the 2012 U.S. Olympic team, Gausha (22-3-1, 11 KOs) was born in Cleveland, Ohio but now fights out of Encino, Calif. The 35-year-old has faced tough competition throughout his career, having fought former champion Austin Trout to a draw in 2019 in addition to decision losses against former champion Erislandy Lara and top contender Erickson Lubin. Following a KO of Jamontay Clark in March 2021, Gausha most recently lost a decision to Tim Tszyu last year after dropping Tszyu in round one. He will take on the 31-year-old Lynch (12-1-1, 9 KOs), a native of New Jersey who now resides in Los Angeles. Lynch is unbeaten since after his third pro fight, having avenged his only other blemish by winning a unanimous decision over Marcos Hernandez in May 2022 following a draw in their first matchup.

At just 22-years-old, Marshall (7-0, 6 KOs) has quickly shown the skill, power and poise to become a highly regarded prospect in just seven fights. Born in Landover, Md., and now fighting out of Capitol Heights, Md., Marshall is trained by former contender Andrew Council and made a strong 2023 debut in January by stopping Shawn West in one round. He will be opposed by Augusta, Georgia’s DeLoach Dock (19-5, 10 KOs), a veteran who owns victories over previously unbeaten fighters Domonique Dolton, Livan Navarro, Junior Castillo and Dillon Cook. He’s faced top competition at 154 and 147 pounds, having battled former unified champion Jeison Rosario and most recently welterweight contender Eimantas Stanionis in November 2020.

Gogokhia (13-0-2, 8 KOs) will return to the ring after two 2022 clashes against fellow unbeaten Kent Cruz that both ended in draws. A 31-year-old former kickboxing pro, Gogokhia originally hails from Zigdidi, Georgia and now resides stateside in Woodland Hills, Calif. He takes on Liberia’s Teah (18-4-1, 8 KOs), who most recently scored a first-round knockout of Larry Fryers in September 2019. Now residing in Philadelphia, Teah owns victories over current 130-pound world champion O’Shaquie Foster and super lightweight contender Kenneth Sims Jr.

The non-televised undercard will also include Dallas-native Miguel Hernandez (6-0, 6 KOs) in a six-round middleweight fight taking on Dario Guerrero (1-3-1) and unbeaten featherweight Albert Gonzalez (3-0, 1 KO) facing Joseph Cruz (3-5, 1 KO) in a six-round showdown.

Rounding out the action is undefeated lightweight prospect Anthony Cuba in a six-round lightweight duel against Florida’s Darel Harris and unbeaten super middleweight prospect Daniel Blancas battling Kansas’ Kynndale Prather in a four-round attraction.
