Parramatta winger Maika Sivo is facing a one-game suspension for his high tackle on Storm's Jahrome Hughes, which was graded careless.
Sivo can accept a one-match ban with an early guilty plea, which would rule him out of the Eels' matchup with the Cowboys on Saturday.
An unsuccessful challenge would see the ban upped to two games, meaning he would also miss the round 11 game against the Panthers.
Meanwhile, Rooster Jared Waerea-Hargreaves and Rabbitoh Junior Tatola can avoid suspensions for their respective dangerous contact and careless high tackle charges with early guilty pleas.
