Birmingham City 0
The FA Cup-tie at Birmingham was in its 94th and final minute when substitute Matt Jarvis came within an inch or two of putting Wolves through to the fourth round of the competition.
But Blues keeper Colin Doyle touched the winger's effort onto the inside of the post and then beat away Steven Fletcher's follow-up header to earn his side a replay at Molineux.
Eggert Jonsson made his debut as one of four changes from the team that started against Chelsea. Dorus De Vries was named as keeper with Sylvan Ebanks-Blake and Michael Kightly, back from his Watford loan, also coming in.
Dropping out were Wayne Hennessey, Dave Edwards and Emmanuel Frimpong who were all named as substitutes, and Adam Hammill.
City kicked-off attacking the Railway End of St Andrews that housed around 2,500 travelling supporters.
There was an early chance for Jonsson when Guirane N'Daw headed a Stephen Ward throw into his path but the Icelander's shot was too high.
Wolves did most of the early pressing without unduly worrying Doyle in the City goal, but Roger Johnson, on his first return to his former club, had to head behind a Wade Elliott free-kick.
Jordon Mutch scooped a first time shot over the bar after he had met Nathan Redmond's centre, and Johnson headed over following a Kightly corner at the other end.
After 24 minutes, De Vries had little trouble in collecting a low, 30-yard drive from Mutch before Johnson's afternoon ended unhappily when he landed badly after an aerial challenge with Adam Rooney.
The defender was in obvious pain and he was helped off to be replaced by Kevin Foley who moved into the right-back slot with Richard Stearman joining Christophe Berra in central defence.
A short through ball from Jonsson found Ebanks-Blake and he turned quickly and toe poked the ball towards goal where Doyle blocked with Curtis Davies completing the clearance.
Half-Time: Blues 0 Wolves 0
Seconds after the restart, Doyle deflected an Ebanks-Blake shot over the bar but the striker was adjudged offside anyway.
Both goals then survived dangerous moments within a five minute spell. After 54 minutes the ball fell nicely for Rooney inside the Wolves box. His shot had power and direction but Jonsson threw himself in front of the ball to block.
Then Foley sent Kightly away on the right and his low cross rolled invitingly in front of Ebanks-Blake but he shot over the bar from 15-yards.
Davies was shown the yellow card after tripping Kevin Doyle some 22-yards out. Karl Henry rolled the ball back to Stephen Hunt who flicked it into the air to set a volley up for himself. But his effort was too high.
Both sides made a change in the 69th minute with Jarvis coming on for Hunt and Jean Beausejour for Mutch.
A combination of Berra and Stearman managed to block a shot from Redmond and when the loose ball ran to Rooney his low effort was kept out by De Vries.
Wolves made a final switch when Fletcher replaced Doyle for the final stages of the game.
Jonsson blocked a Beausejour volley before Rooney went into the book after one foul too many for referee Mike Dean.
With the game about to move into stoppage time, Redmond hit a low shot that De Vries needed two attempts to hold on to.
Ward headed straight at the keeper from Kightly's corner before the drama in the dying seconds.
Jarvis cut in from the left and unleashed a shot that was destined for the far corner until Doyle got his fingertips to the ball to touch it onto the post.
The ball looped up into the air and Fletcher headed towards goal only for Doyle to save the day again for the home side. He hadn't regained his feet but he still managed to beat the ball away to deny Fletcher and Wolves.
