Magee attracted interest from Manchester United and Aston Villa as a youngster, but a string of bad injuries saw him opt for a move abroad in a bid to prove himself.
After a prolific three years at Rockhurst University in Missouri, Magee headed to Iceland where he played for UMF Tindastoll before he was snapped up by professional top-flight side Fjolnir.
It is a surprising move from Town and one that has come about thanks to midfielder Jack Roberts, who is a close friend of Magee’s.
“He’s coming in out of the blue,” said Town boss Carl Adams.
“He’s looked very good in training. He will work hard for us and run the channels.
“We certainly need the bodies and the door is open for him.”
Adams is likely to hand Magee his debut at Histon on Saturday.
