Bolton Wanderers have come from behind to lead Birmingham City at the end of the first half at the Reebok Stadium.
The visitors broke the deadlock on 11 minutes when Nikola Zigic headed beyond Adam Bogdan from six yards following a pinpoint cross from Chris Burke.
Wanderers responded well to falling behind and deservedly levelled 16 minutes later, Tyrone Mears finding Marcos Alonso, who nodded home from close range.
The hosts completed the turnaround on 33 minutes courtesy of a brilliant piece of play between Kevin Davies and Lee Chung-Yong.
Davies found Lee with a perfectly-weighted through ball and the South Korean international beat Jack Butland with a clinical finish.
