Catalans Dragons hooker Michael McIlorum has been suspended for a total of six matches for offences in last Friday’s match against Leeds Rhinos.
McIlorum pleaded guilty to a high tackle charge but challenged the grading.
However, the Operational Rules Tribunal upheld that grading and imposed a two-match suspension, in addition to a £500 fine.
He also pleaded guilty to a charge of Other Contrary Behaviour and also challenged the grading.
In that case, it was agreed to reduce the grading to D, and imposed a four-match suspension, with no fine.
