Castleford's in-form winger Justin Carney has been suspended for the third time this season after being found guilty of a grade C offence.
The 30-year-old Australian had already missed four games this season and will miss the Super League clashes with Leeds, Hull and Wigan after appearing in front of the Rugby Football League's disciplinary committee.
Carney was penalised after a dangerous throw on London Broncos forward Shane Rodney during Castleford's 30-30 draw at the Twickenham Stoop.
The Tigers winger had scored seven tries in their last five games and begun showing why Castleford were so keen to bring him to England from the Sydney Roosters last off-season.
Carney was given a two-match ban in March after being cited for punching and served another suspension in April after being found guilty of a dangerous throw.
