Police are investigating after a Hampton Park Redbacks player was allegedly coward-punched from behind on Saturday 13 April at Robert Booth Reserve.
While waiting on the sidelines during their reserve-grade game against the Doveton Doves, a spectator recording showed a man in a black hoodie hitting a player from behind, dropping him to the ground.
The hooded man could be seen making his way through the gap in the fence, then moving behind the player where his fist connected with the victim on the right side of the face.
The 28-year-old victim fell to the ground, clutching his head while fellow players and bystanders stood in shock and came to his aid.
The man suffered a facial injury and was taken to hospital with non-life-threatening injuries.
Victoria Police were contacted and said the incident was currently undergoing investigation.
