Ex-Spurs, Newcastle fullback Carr announces retirement
He has called time on his career after more than 400 league games for Spurs, Newcastle and Birmingham.
Full-back Carr, capped 44 times by the Republic of Ireland, made his debut for Tottenham in 1993.
Carr, who has a knee problem, said: "I'm going on 37 and now is the time to bow out.
"I felt OK in pre-season, but three operations in 18 months told me my knee has had enough."
