The Dragons have been unsuccessful in attempting to challenge the grading of a charge incurred by Jack de Belin against the Sea Eagles on Saturday.
De Belin was hit with a grade two dangerous contact charge by the match review committee for 65th-minute incident involving Sea Eagles winger Chrisian Tuipulotu in Round 22 at WIN Stadium.
Due to prior loading, the charge would have incurred a three-match ban with an early plea.
A successful challenge of the grading would result in de Belin incurring a $3,000 fine instead of a suspension.
However the judiciary on Tuesday night upheld the grade two charge. As a result the 32-year-old will miss the Dragons' next four matches.
