Former Huddersfield head coach Jon Sharp has been appointed as technical adviser by the Rugby Football League.
Ex-Hull FC player Sharp had joined the organisation on a consultancy basis, having previously worked as part of the coaching set-up with Great Britain, Hull FC and – last season – as Brian Noble's assistant at Crusaders.
RFL chief operating officer Ralph Rimmer said: "Jon is a coach and former player with considerable experience whose contribution as a consultant will complement the work already being done at the RFL.
"His presence, together with other changes that have been made internally since the end of last season, demonstrates the RFL's determination to raise the bar in everything we do."
Sharp will advise Super League match officials on playing trends within the game and offer them assistance from a coach's perspective. He will also serve on the RFL's disciplinary panel.
