The 19-year-old forward, who joined the 'Gers in the Summer from Knockbreda, made 4 appearances for the Club before suffering a bad ankle injury.
To continue his development, Montgomery now joins Gary McKee’s side where his progress will be closely monitored.
Manager Stuart King explained,
"Jack has joined islandmagee to get some valuable game time towards the end of the season. We look forward to watching his progress and will be keeping a close eye on him. Thank you to Gee and all at Islandmagee for their help with this."
Good luck, Jack!
