Jon is a player of pedigree, having made his name mostly in the National League.
The striker started his playing days in the second tier with hometown club Sheffield Wednesday before really finding his feet with Burton Albion in the Conference.
He truly showed his potential following a move to Halfax Town in 2007, scoring 26 goals in all competitions in his one season there, earning himself a move to the Football League with Rochdale.
Things didn't quite work out there for Jon, who is known for his aerial ability, strong finishing and high work-rate.
Three loan spells with different National League clubs followed before he found a home for himself in the North East with Gateshead, spending two prolific campaigns with the Tynesiders, the second of which saw him score 35 times.
Again, he was then on the move, this time to Luton Town, before returning in 2014 to Gateshead.
In 2016, having been released by the Tynesiders, Jon made the decision to drop into part-time football, which works in conjunction with his role as a coach in Middlesbrough's academy.
The project at Mariners Park eventually tempted him to move to South Shields, and he put pen to paper in July 2016.
