Coventry have completed the signing of Birmingham goalkeeper Colin Doyle on an emergency month's loan.
The 25-year-old is expected to make his debut in Tuesday's Carling Cup first round match against Morecambe as cover for Keiren Westwood who is on international duty with the Republic of Ireland.
Doyle is also an Ireland international and has represented his country at every level, making one senior appearance in a 1-1 friendly draw against Ecuador in 2007.
He joined the Blues as a 16-year-old and having had loan stints at Millwall and Nottingham Forest he was a major player in helping City to Premier League promotion in 2007 making 19 Championship starts.
However, the stopper has seen his first-team chances limited in the top flight and he is currently third choice at St Andrews behind England's Ben Foster and Northern Ireland's Maik Taylor.
