He most recently played for Grays Athletic on loan from Lincoln City.
In the summer of 2007 Lincoln were forced to release Wilkinson as a broken leg had ended his career aged 21.
He graduated from York St John University in November 2010 with a bachelor's degree in Physiotherapy, after his studies were funded by the Professional Footballers' Association as part of their programme of post-career training for current and former professional footballers and academy players.
He now lives in his home town of Lincoln and works as a physiotherapist at Lincoln County Hospital for the United Lincolnshire hospitals NHS trust.
