Graham with his favourite Town player, Andrew Boyce.
Graham, who has supported the club home and away for over 40 years, was invited down to Tuesday's training session to meet the players and Paul Hurst. Graham was presented with a special Mr Graham shirt by the Town boss and he will also lead out the teams at Wednesday's friendly game at Cleethorpes Town.
Sue Mullen, the wife of Town director Lee Mullen, has started a Crowdfunder campaign (below) to try to raise money to help Graham's family with some of the travel costs to and from Castle Hill hospital.
