He was loaned out to Halifax Town in 2002 and became an instant hit at The Shay when he notched up eight goals in eighteen games.
However amongst much expectation the youngster failed to produce the form that had earned him a permanent contract at the Yorkshire club.
Ryan was loaned out to Gainsborough Trinity for the remaining quarter of the 2004–2005 season before being released by Halifax in the summer.
Despite interest from Gainsborough, Mallon opted to stay in the Conference league and signed with York City.
It was at The Northolme where Mallon would finally find his feet and has been an integral part of the club setup since joining.
