Birmingham City have confirmed the signing of Stephen Carr.
The former Republic of Ireland defender has been out of football since leaving Newcastle last summer.
He was linked with a host of clubs before officially retiring in December last year.
But he began training with Birmingham earlier this month and has now agreed an initial one-month deal at St Andrews.
"We've been looking to strengthen the full-back position and are pleased to bring in Stephen as he brings with him great experience," said Birmingham boss Alex McLeish.
"He has not played for a while but there's no doubt he is a quality player who can definitely bring something to the side once he is fully match fit."
Carr could now be in line to make his Birmingham debut against Crystal Palace on Tuesday.
