He played his club rugby league for Marseille, Sporting Olympique Avignon XIII and Lezignan, becoming the most capped International, with 37 games for France.

Merquey originally played rugby union, where he also represented France, in a total of four games against England, Wales, Ireland and Scotland in 1950.

Merquey played superbly throughout the three Test series, won triumphantly by France 2–1 before over 157,000 spectators.
