A Melbourne suburban football club is under investigation over allegations that club officials made players strip naked and run around an oval as punishment for poor performance in a practice game.

The Age has been told some of the East Burwood Rams players, who compete in the second division of the Eastern Football League, were as young as 17.

Concerned parents were among those who prompted an official complaint.

The Eastern Football League said they were investigating the incident, understood to have occurred during a Thursday night training session on May 22.

The league said it was not contacted by the club until this week.
