The 911 Paramilitary Club boxer Ung Vireak beat the Brazilian Paolo, who was replacing his injured compatriot Leonardo, by a points decision after a highly defensive contest.

Other results from the international fight night included a third-round knockout victory for Thailand’s Buakaw Banchamek, who unleashed a flurry of knees and punches on Harlee Avison, leaving the Australian down and out in the corner.

Kruth Meanchey Club’s Aim Vutha stopped Brazil’s Renan in the first round with a vicious knee to the side, while Bheut Kam, of Saravorn Keila Club, threw a kick at Brazilian Jackson Alves de Souza during round two of their match but was caught in the knee by a counter-kick that connected with such force the Cambodian was unable to continue.
