GWS CO-CAPTAIN Phil Davis says the Giants are rallying around Toby Greene after the latest chapter in a tumultuous month for their teammate, also hitting out at perceived lack respect for him.

The estranged father of the Giants' forward has been remanded in custody after allegedly headbutting a policewoman at Saturday's Grand Final.

Michael Greene appeared in Melbourne Magistrates' Court on Sunday, charged with intentionally causing injury, resisting police and assaulting police.

The 60-year-old was also charged with public drunkenness and committing an indictable offence while on bail. He will face Ringwood Magistrates' Court on Wednesday.

Toby Greene joined his teammates on Sunday at a fans' day at the club's headquarters in western Sydney.

Asked how Greene was doing after hearing the news of his father's situation, Davis said "It's obviously not the perfect scenario for (Toby) to be in.

"We'll put our arms around him. He's a terrific person so what we'll do is support him."

Greene made headlines throughout the Giants' finals campaign.

He was fined $7500 for misconduct against Western Bulldogs star Marcus Bontempelli, including making contact with his face in an elimination final.

The next week, Greene was given a one-game suspension for making unreasonable or unnecessary contact to the eye region of Brisbane's Lachie Neale in a semi-final and missed the Giants' preliminary-final win over Collingwood.

Greene is no stranger to being targeted by fans of opposing teams. He was booed frequently by Richmond supporters when he had the ball during the Grand Final.

"From my point of view, people make a huge amount of assertions about Toby without knowing the man," Davis said.

"In my opinion, some of them are completely unfair and unfactual too.

"It's disappointing at times, as a teammate and a good friend of him, that he gets treated with what I think is a lack of respect."
