The midfielder underwent surgery last month and will miss the remainder of 2012/13.
â€śWe hope to have him back in action for next season and there will be a different role for him along the lines of how he played this season, sitting in front of the back four as the holding midfielder.
â€śDarren coped well during the last few months and he made a return to football [after his initial spell on the sidelines] with 10 senior appearances. His treatment was going well, but the problem surfaced again and the advice was [to] have surgery. The decision was taken with Darrenâ€™s long-term health in mind just as much as getting back to his career.
â€śIt hasnâ€™t been an easy journey for him, but he has shown great courage. There isnâ€™t a nicer boy at the club and he's a star professional. All his team-mates wish him well and I am sure the fans join me in wishing him a good recovery and a speedy return to football.â€ť
