Spruce signed for The Blues back in September and has made 28 appearances for the club to date, scoring four times in the Southern League.
The 24-year-old opened his account for the season with a goal in our 2-2 draw to Kettering Town at Grange Park shortly after signing.
In December, Spruce scored the decider in our first-ever home win at Step-Three then we beat Berkhamsted for a second time this season.
We would like to wish Spruce all the best for the future!
