West Coast forward Liam Ryan could face a monetary penalty after gesturing his middle finger during Saturday night's loss to Essendon.

Following a fracas with Bombers defender Mason Redman, Ryan was caught on the live broadcast 'flipping the bird'.

While it is unknown who Ryan was directing the gesture towards, the Eagles high-flyer could face a fine for his actions.

Richmond superstar Dustin Martin was fined $7,500 - $5,000 of which was suspended - for making abusive gestures towards Greater Western Sydney players in April, 2019.

Martin apologised for his actions via Social Media after the fine, stating he was frustrated at the time.

"Frustrating one on the weekend !! I understand my reaction is not a good look for the game.. I apologise for my actions . Thanks," Martin tweeted.

โ€œMaybe the AFL considers a $1000 fine for him โ€ฆ Itโ€™s not a hanging offence," Ralph said.

The incident follows a forgetful evening for the Eagles, who gave up a 29-point lead to loss their first home game of the season.

West Coast will be sweating on the results of star midfielder Tim Kelly, who was subbed out of the match with a knee injury.
