Eels back-rower Manu Ma'u has been found guilty of a dangerous throw charge at the NRL judiciary.

Eels forward Manu Ma'u will miss his side's Round 21 clash with the Wests Tigers after he was found guilty of a grade one dangerous throw charge at the NRL judiciary on Wednesday night.

Ma'u was cited for an incident involving Titans playmaker Ash Taylor in Gold Coast's win over Parramatta in Round 20, with two prior non-similar offences in the past two years not helping his cause.

Generally a back-rower, Ma'u had again been named in the centres on Tuesday to cover injuries to Parramatta's backline, with his replacement to be confirmed an hour before kick-off on Saturday night.
