London: Second-tier side Birmingham City knocked Premier League Wolverhampton Wanderers out of the FA Cup after Wade Elliott broke the deadlock 16 minutes from the end of the third round replay to secure a 1-0 away win.
Elliott hit the post after latching on to a cross from the right but made no mistake when he converted the rebound from close range while lying on the ground.
City will now travel to third division Sheffield United for their fourth-round match.
