Lester Martínez will step into the ring on Saturday 29 August for the 22nd professional fight of his career, headlining a boxing card at the Galen Center of the Universidad del Sur de Los Ángeles in Los Ángeles, California, United States. His opponent will be the unbeaten Croatian Luka Plantić.
The bout matters now because Martínez is already in Los Ángeles and the promotion is moving into its final stretch. Martínez and Plantić even held a faceoff to publicize the fight, a sign that the main event is settled and the focus has shifted to the ring.
For readers looking for the basic details, the timing is straightforward: the fight is set for Saturday 29 August, and it will be the main bout on the card at the Galen Center. What remains unresolved is the broadcast. The confirmed information does not name a channel or streaming outlet, so anyone planning to follow Martínez will still be waiting on that piece.
Martínez’s trip also overlapped with a separate Guatemalan gathering in the city. On Thursday 27 August, he met with Adriana Ruano and Jean Pierre Brol in Los Ángeles, where the Comité Olímpico Guatemalteco said the two shooting medalists from París 2024 gave details about their participation in Festival Chapín Los Ángeles 2026.
That festival is scheduled for Saturday 29 and Sunday 30 August at Lafayette Park Place in Los Ángeles, and the Olympic committee described it as an approach to the Guatemalan community in the city. It also said the activity is one of the first before the 2028 Olympic Games in Los Ángeles. That gives Martínez’s fight week an unusually crowded backdrop: a major boxing card on one side, and a community event tied to Olympic momentum on the other.
For Martínez, the next confirmed moment is simple. He fights Plantić on Saturday night, and with the main-event slot and the 22-fight milestone, the result will carry more weight than a routine appearance on the schedule.
