May was stood down by the club last week following his conduct on social media in the wake of the club's grand final win over South Sydney.

The Penrith board met on Wednesday where they issued the 25-year-old with a show cause notice.

"At today's meeting of the Panthers board of directors it was determined May's conduct constituted a serious breach of his NRL playing contract," the club said in a statement.

"In accordance with disciplinary protocol, May will have the opportunity to appear before the board next Wednesday before a sanction is imposed."

The utility was fined $7500 by the NRL for the post which "did not align with the values of the game" as he made reference to his conviction for recording an intimate image without consent.

A post showed a photo of May alongside coach Ivan Cleary outside a court in 2019 captioned with lyrics by rapper Drake which read: "And the dirt that they threw on my name turned to soil and I grew up out it. Time for y'all to figure out what y'all gon' do about it."

May was lucky to avoid jail at the time and missed the entirety of the 2019 season after being stood down by the NRL.

Magistrate Robyn Denes described his behaviour as "morally reprehensible" and sentenced him to 300 hours of community service.

May, who debuted for the club in 2017, has scored 10 tries in 56 games for the Panthers.
