Jon Sharp played loose forward in Hull FC's 24-31 defeat by Castleford in the 1986 Yorkshire Cup Final during the 1986–87 season at Headingley, Leeds on Saturday 11 October 1986.

In 2004, Sharp's début season as coach of Huddersfield the club finished 7th in Super League and made an appearance in the semi-finals of the Challenge Cup for the first time since 1971.

In 2006, Sharp led Huddersfield to their first Challenge Cup final in over 40 years, including a 30-12 win over Leeds in the semi-finals held at Odsal.

After a nightmare start to 2007's Super League XII in which Huddersfield lost all of their opening 7 games, some might have expected Sharp's job to be under threat.

As a Technical Adviser he will offer a coach's perspective of playing trends to match officials, as well as serving on the Rugby Football League disciplinary panel.
