The 23 year old, who is the older brother of fullback Alex, returns to the Lane following a spell in America, where as well as completing a scholarship has played for Lionsbridge, Seacoast and Portland Phoenix.
Luke was one of Robbie Mason’s first signings originally joining the club in December 2016, scoring three goals in thirteen appearances to help the Greens survive relegation at the end of the season, and has also been associated with St Neots Town, Godmanchester Rovers, Histon and Ely City.
Luke has received his international clearance and could make his second debut during the Boxing Day fixture away to Bury Town.
