HUDDERSFIELD Giants have admitted they remain in the dark over what action the Rugby Football League may consider taking over head coach Jon Sharp's Challenge Cup post-match blast at referee Ronnie Laughton.

The RFL last night announced their Disclipinary Commissioner will examine whether Sharp should be referred to Red Hall to explain his comments in the wake of Sunday's 26-22 Cup defeat at the hands of St Helens.

Sharp used video evidence at the post-match press conference to highlight several key refereeing decisions which went against his side and denied them victory.

But now the Galpharm chief is facing the threat of the RFL taking action against him over his outburst - although club officials have no idea what the nature of the case might be.

"Like everyone else, we were informed by the media that the RFL are looking into the comments made by Jon," said Giants football manger Stuart Sheard.

"We have as yet received no official notification as to what the RFL will be investigating.

"All we have received so far is a fairly vague press statement announcing Jon is under investigation.

"It could be that we are told nothing more unless Jon is called to RFL headquarters at Red Hall to explain his actions.

"But, to be honest, this is the first time we've been investigated in this manner and we are in the dark as to the exact procedure.

"What we'll have to do is await any further information from the RFL to see what's happening."

As well as the two video clips highlighted by Sharp in the press conference - the Paul March disallowed try and the dubious one awarded to Saints' Darren Albert - the Giants chief has claimed a further EIGHTEEN contentious refereeing calls which went against his side.

Those included the scoring of Vinnie Anderson's try, which on video looked to have come from a forward pass from Ade Gardner.

But while Sharp is facing an anxious wait over what action the RFL may take against him, he is working flat-out on preparing for Friday's home Super League game against Wigan (8.00).

The Giants named their 20-man squad today and included stand-off Chris Thorman.

The Huddersfield playmaker was struggling in training with a back strain and it was decided not to risk him.
