Warrington forward Ben Westwood has been handed a four-match ban for the head butt that earned him a red card during his side's 25-12 win over Wigan.
Westwood, who was charged with a grade D offence by the Rugby Football League's match review panel, admitted the offence but challenged the grading when he appeared at a disciplinary hearing.
The tribunal found the grading was correct and appropriate and imposed a four-match ban and a fine of £500.
Westwood, who served a two-match ban for a dangerous tackle in the Wolves' opening game of the season, will start his latest suspension when Warrington visit Wakefield on Thursday.
