Winger signs new deal.
Players' Player of the Year in 2012/13, Gavin got off the mark at the weekend with two goals against Fleetwood, taking his tally to eleven in his time with the U's.
He had previously enjoyed a successful loan spell with the Weston Homes Community Stadium side, and has now played 94 times for the club in league and cup competition.
Gavin, who joined the U's from Watford on a permanent basis in the summer of 2012, has penned a two and a half year deal to take him through to the summer of 2017.
Colchester United winger Gavin Massey has extended his stay at the club, having signed a new contract on Thursday afternoon.
