Eduardo Chapolin will make his UFC debut this Saturday after Jose Ochoa was injured and pulled from the flyweight bout with Charles Johnson at UFC 330 in Philadelphia. The replacement was announced by Johnson on Instagram, and the fight is set for a catchweight of 130 pounds at the Xfinity Mobile Arena.
The new matchup matters because the original Johnson-Ochoa bout was on the main card, but it is still unknown whether Johnson against Chapolin stays there. That uncertainty sits beside a bigger shift: Chapolin is getting into the UFC on three days' notice, a sharp turn for a 30-year-old Brazilian flyweight who had not been handed a contract after beating An Tuan Ho on the Contender Series.
Chapolin arrives with a long route behind him. Between 2015 and 2022, he built a record of ten wins and one loss in the Brazilian MMA scene before signing with LFA in 2022. He later earned a title shot after a win over Leandro Soares and closed out 2023 by beating Cody Davis in the fourth round by TKO to win the LFA flyweight championship.
He kept collecting results after that. Chapolin defended the LFA title with a first-round knockout over Igor Siqueira, entered the 33rd season of The Ultimate Fighter and lost his first fight against Joseph Morales, then kept training with Daniel Cormier after the season. Last year in August, he defended the belt again by knocking out Devon Lozej in the first round, then took a short-notice Contender Series fight just over a week later and beat An Tuan Ho by unanimous decision. Dana White did not award him a UFC contract that night.
Johnson brings his own stakes into the fight. This will be his fourth fight of 2026, a year in which he beat Bruno Silva in a close fight but was finished by Alex Perez and Asu Almabayev. The loss to Almabayev cost him a place in the top 15 of the flyweight division, even as he remains the only man to beat Joshua Van in the UFC after knocking him out in the third round. He also knocked out Lon’er Kavanagh in Shanghai last year.
For Chapolin, the debut is sudden but not random. He has already shown he can accept short notice, go the distance when needed and finish when the opening comes. What is left to sort out is the fight’s position on the UFC 330 card, and that answer may matter almost as much as the debut itself.
