O'Halloran's career has been plagued by injuries
Republic of Ireland defender Stephen O'Halloran has agreed to sign a contract with Carlisle on 1 August.
The ex-Aston Villa trainee, now 23, was
released by Coventry this summer
after 13 appearances in one season there.
He will sign a one-year deal at Brunton Park with the club having the option to extend that for another season.
Boss Greg Abbott told the club website:
"We think Stephen is a player with a bit of quality. He's had a fantastic upbringing in the game."
