Queensland Roar veteran Danny Tiatto was again sent off in Friday night's minor semi-final win over the Central Coast Mariners.

But it was his reaction after receiving the red card that could land him in hot water.

The former Manchester City midfielder was sent off for allegedly striking Mariners forward Dylan Macallister and was furious towards referee Ben Williams after the second yellow card was produced.

The Football Federation Australia believes that Titatto breached the National Code of Conduct and have asked for an explanation regarding the incident.

A decision will not be made until the 11th of February.
