Carlisle release Craig Curran and Stephen O'Halloran

Stephen O'Halloran

Carlisle United are to release former Aston Villa defender Stephen O'Halloran and striker Craig Curran when their contracts expire this summer.

O'Halloran, 24, was restricted to just five appearances this season due to a knee cartilage injury following his arrival from Coventry in June 2011.

Curran, 22, scored eight goals in 69 games following his move to Brunton Park in the summer of 2010.

"They leave with our very best wishes," boss Greg Abbott told the club website.

He added: "Both lads have worked hard and they've been a pleasure to have around."

Carlisle have offered new contracts to James Barrett, Mark Gillespie, Danny Livesey, Lubomir Michalik, Peter Murphy, Frank Simek, Tom Taiwo and Francois Zoko.
