Nicknamed 'King Kazu', Miura joined the second-tier club on loan from Yokohama FC earlier this year and came on in the 90th minute of a 4-1 win against Academico de Viseu.
Miura's appearance, the league said on it's website, made him "the oldest footballer ever to play in Portuguese football, with 56 years, one month and 24 days."
