Hull KR prop Mitch Allgood has been handed a one-match ban for making deliberate contact with a referee.
Allgood was charged by the Rugby Football League's match-review panel with a grade B offence, after remonstrating with Richard Silverwood during the recent Magic Weekend in Newcastle.
The forward was unhappy with Silverwood's decision to award a try to Hull winger Curtis Naughton during his side's 28-16 derby defeat.
The Australian forward submitted an early-guilty plea and will miss KR's match against Catalans Dragons in Perpignan this Saturday.
However, Rovers will have hooker Shaun Lunt available for the trip to France after he admitted a grade A offence in the same match.
Lunt made a dangerous throw on prop Liam Watts but was told he faces no further action.
Meanwhile, Salford winger Justin Carney will lose his ever-present league record after submitting an early-guilty plea to a grade B dangerous throw on Chris Bridge of Widnes.
Carney was given a one-match ban ruling him out of Wakefield's visit to the AJ Bell Stadium on Friday.
