Mihai Vardală played rugby football for the Romanian team that won a bronze medal at the 1924 Paris Olympics, although little is known of his life. There were only three teams in the 1924 Olympic tournament and the Romanians won the bronze medal despite losing both of their matches badly, losing 61-3 to France, and 37-0 to the United States. Vardală played for Stadiul Român in București. He played as a winger against the USA, and a flanker versus France, which were his only two international appearances.
