GREATER Western Sydney star Toby Greene is at risk of missing Friday night's clash against the Western Bulldogs after his alleged headbutt on Sydney opponent Isaac Heeney was captured on behind-the-goals vision.
The Match Review Panel is scrutinising Greene's actions on Monday after he was reported in Saturday night's clash at the SCG by umpire Curtis Deboy, who was on the spot when he transgressed.
The All Australian forward's actions were not caught on the Fox Footy broadcast, but behind-the-goals vision shows him grappling with Heeney before leaning into the Swans midfielder with his head.
Full match coverage and statistics
If the MRP deems there was sufficient force in Greene's actions to constitute a report, it is likely to be graded intentional conduct with at least low impact to the head, resulting in a one-match ban.
In the event the impact was graded as medium, Greene would miss two matches.
The charge would be Greene's third this season after being found guilty of striking Port Adelaide's Dan Houston off the ball in round four and misconduct against North Melbourne's Sam Gibson in the JLT Community Series.
He was fined for each of those charges, meaning he does not have a bad record that would result in an extra week being added to his next transgression.
The 23-year-old has been under the close watch of the MRP after six prior charges in the past six seasons.
The Giants will stage their inaugural Friday night match in round six, hosting the Bulldogs in Canberra in a rematch of the classic 2016 preliminary final.
Greene, one of the club's two All Australians from 2016 with Heath Shaw, has kicked 17 goals in five matches and averaged 18.3 possessions in a strong start to the season.
