Penrith captain Matt Moylan has been axed and sent to play reserve grade after breaking team curfew following Saturday's NRL loss in Melbourne.
Moylan is one of three players cut from the side for Friday's clash with South Sydney following a "breach of team protocol", along with outside backs Peta Hiku and Waqa Blake.
It's understood the players were caught drinking late after their 28-6 defeat.
In a statement on Tuesday, the club said the trio will miss Friday night's home clash with South Sydney and will instead face Newcastle in the NSW Cup on Saturday.
The suspension is not the first time Anthony Griffin has stood a player down since his he began at the club last season.
