Callum made his first Development League appearance in April 2015, aged only 15, in a fixture against Motherwell. He enjoyed a breakthrough campaign where he took to Development League football with ease in the first half of the campaign. His form faded slightly in the second half of the campaign as the amount of games took their toll, but the energetic midfielder proved to be a valuable asset in the Jags team and will be looking to build on a promising first season.
Contract Expires: May 2018
