The football governing body FIFA says a Tahiti player failed a doping test at the Confederations Cup in Brazil.
FIFA did not identify the player or details of the violation.
However, Radio 1 in Tahiti says the player suspected of doping is Vincent Simon.
The player's sample was taken after Tahiti lost 8-0 to Uruguay in June.
FIFA says the player has been provisionally suspended for 30 days.
FIFA said the player and the Tahitian Football Association have two weeks to collect evidence and submit a statement to the governing body.
