The Rugby Football League has confirmed it is continuing its investigation into an allegation newly-crowned league leaders Huddersfield made an illegal approach for Bradford prop Craig Kopczak towards the end of last season.

The Giants were cleared of any wrongdoing following Bradford’s initial complaint.

But the RFL re-opened its investigation after conflicting evidence surfaced during the  recent court case in which Keith Mason successfully sued Huddersfield for wrongful dismissal.

The RFL are also looking into the conduct of fellow Super League club Salford  during their recent hectic transfer activity.

The sport’s governing body will examine allegations brought by Wakefield that the City Reds made illegal approaches to “three or four” of their contracted players.

Wildcats coach Richard Agar claimed in the wake of his club’s sale of scrum-half Tim Smith to the City Reds at the weekend that Salford had also directly made contact with other players at Wakefield.

“We notified the Rugby (Football) League quite a while ago about this,” Agar said.

“They will deny it and there is a third-party agent working for them but I know players under contract have been approached.

“That’s a disappointing mode of  operation. We know certain things go on but sometimes there are ways and means of doing things.”

A spokesman for the RFL said an  investigation would be launched once the Wildcats provide the evidence to support their claim.

But Salford say they are confident they will be cleared by any investigation.
