The AFL will look at match and security vision after a Western Bulldogs fan allegedly poured beer over controversial Greater Western Sydney star Toby Greene.
The incident happened in the Giants' player race at Etihad Stadium as they left the field after Friday night's controversial 48-point win over the Bulldogs.
Greene is again under match review panel scrutiny. Hhe was reported for rough conduct after his right boot caught Luke Dahlhaus in the mouth.
The third-term incident in a marking contest forced Dahlhaus off the field with a cut mouth.
Already a villain to opposition fans, Greene was the subject of booing from Bulldogs fans throughout the match.
The Giants lodged an official complaint with the AFL on Saturday morning about the alleged beer incident.
"Obviously Toby's a close mate of mine and he said that something happened on the way down the race," teammate Heath Shaw told SEN.
"I don't think the Bulldogs fans were too happy with Toby after the game."
Giants coach Leon Cameron defended Greene post-match.
In his first game back from a two-match ban, Greene faces his third suspension of the season if the MRP rule against him.
"I understand there's going to be a lot of hysteria about Toby," Cameron said after the match.
"But clearly he has got his eyes on the ball so what he's done is protected himself. He's got his eyes firmly placed on the footy.
"These little unfortunate things happen in footy.
"Obviously the powers that be will look at it ... but they need to judge Toby Greene on his merits."
Greene has been fined twice this year and missed a total of four games through suspension --- two games for striking the Dogs' Caleb Daniel in round six and another two for striking Richmond's Alex Rance.
The latest incident was a rare lowlight in a strong second-half performance from the Giants, who strengthened their hold on second spot.
GWS led a see-sawing contest on by four points at halftime then surged to victory on the back of six unanswered goals in the third quarter.
"It was a terrific win," Cameron said.
"I'm really proud of the players because they haven't experienced much Friday night footy in Melbourne when the spotlight is right on you.
"No doubt our form has been up and down but we've won our last three games now, which is pleasing."
GWS take on West Coast at Spotless Stadium in round 22.
