Eels forward Tepai Moeroa has been charged by the NRL Match Review Committee following an incident during Saturday's loss to the Knights.
Moeroa has been charged with a Grade Three Shoulder Charge from his bump on Knights forward Chris Heighington.
With an early plea, Moeroa would miss three weeks, while a guilty finding would put him out for five weeks.
The bottom-placed Eels will take on the Cowboys next Saturday at TIO Stadium.
