The match saw both teams come from behind twice, with Fer López scoring in the third minute for Wolves and Jay Stansfield equalising in controversial circumstances. Ladislav Krejci then gave the visitors the lead again just after the half hour, but Jackson Tchatchoua's own goal levelled the score at 2-2.
The Cameroon right-back's moment of individual error set the tempo for the rest of the game, as Wolves were unable to capitalise on their chances to win the match. Adam Armstrong missed a golden opportunity to win the game for Wolves in the 87th minute, lifting the ball over an open goal from 10 yards out.
The draw means that Birmingham City extend their unbeaten start to the league season, while Wolves remain in the automatic promotion frame.
