Luke was released from Nottingham Forest in the Summer and has been on trial at Burton Albion and Spanish side Levante.
Luke did feature for The Gingerbreads in pre-season as a trialist in the friendly at Spalding United, coming on as a second-half substitute.
Gingerbreads Manager Ian Culverhouse is pleased to get Luke in, "We were really impressed in pre-season and have been keeping in regular contact with him over the summer. I have been asked about 'the Luke' who came on at Spalding United by supporters, so I'm delighted to be able to get him signed. I'm really pleased with the options he's going to bring us"
The registration was completed in time for Luke to go straight into the squad for tomorrow's Emirates FA Cup tie at Daventry Town.
Welcome to The Gingerbreads Luke!
