In the second of two late signings, the club has also signed young defender Ed Cook.
19 year old Ed was released by Burnley during the summer and then moved back to London.
Cook was originally signed by the Clarets from the Bradfield College football programme, in Berkshire, back in April 2018 and signed his first professional contract.
The signing of Ed now gives Gary some welcome depth in the centre of defence, and he is expected to be available for the match at Chelmsford.
Welcome to the club, Ed!
