The Hull coach, Richard Agar, will learn today whether he will face any action over his remarks about the refereeing of James Child on Friday night.
The Rugby League has been studying a transcript of Agar's furious comments after the 20-18 defeat by Castleford before deciding if he should face charges under its 'Respect' agenda.
The RFL said it had not yet received a complain from Hull about the official's performance.
Hull could face a second head-ache today with the likely suspension of one of gtheir pivotal players. Sean Long was sent off for use of the elbow late in the game - an offence which carries a potential suspension of three to five matches.
Wigan's Jeff Lima, on the other hand, is set to escape with a lesser punishment for the tackle on Leeds' Chris Clarkson which angered many at Headingley on Friday. Lima has been charged with making dangerous contact, which carries a one or two match ban.
Pat Richards, who has not played since rupturing his Achilles tendon in last season's Grand Final, could make his comeback for Wigan against the Catalan Dragons on Friday. The reigning Man of Steel came safely through an under-20s game at the weekend.
The Catalans could have Scott Dureau available for that match despite being stretchered off with his neck in a brace at Warrington.
"The x-rays were all clear, but we'll have to see how he rrecovers," said his coach, Trent Robinson, who could be ttempted to give Thomas Bosc his first game of the season after he too came back successfully in the under-20s.
The Bradford half-back, Danny Addy, will be out for two months after fracturing his thumb.
