Colchester United have handed new one-year deals to defender Tom Bender and goalkeeper Carl Pentney.
Bender, 19, made his U's debut in October 2009 and has gone on to make one further appearance for the club.
The Wales Under-21 player made headlines while at Accrington last year when he suffered a serious head injury during a match against Tranmere, causing the game to be abandoned.
Pentney, 22, played nine times while on loan at Hayes & Yeading last season.
The former Leicester youngster is yet to make his senior Colchester bow.
