Birmingham City have completed the signing of former Bolton Wanderers defender Paul Robinson.
The 33-year-old, who departed the Trotters in the summer, had been on trial with Birmingham since the beginning of the season.
However, he has sufficiently impressed Lee Clark to be offered a short-term contract, which will run until October 26.
"I'd like to thank the Board for allowing me to bring in Paul, an experienced defender who will enhance our playing squad," Clark told the club's official website.
Robinson has also played for West Bromwich Albion.
