Wolves had to come from behind to book their place in the FA Cup fifth-round with victory over Shrewsbury.
Matt Doherty handed the home team an early lead before the League One side equalised with a James Bolton header.
The Shrews then took a surprise lead through Josh Laurent as goalkeeper John Ruddy let the ball slip through his hands for the Premier League club.
But Doherty restored parity in first-half injury time before Ivan Cavaleiro sealed their progress after the break.
The Portuguese forward rolled the ball past Steve Arnold in clinical fashion despite appearing to stumble in the build-up to the goal.
Wolves will now travel to Championship club Bristol City on 17 February for a place in the quarter-final.
Less than convincing Wolves go through
Nuno Espirito Santo made six changes to his side that beat Everton in the Premier League on Saturday, and regulars Raul Jimenez and Joao Moutinho were among those who dropped to the bench.
The hosts raced into a second-minute lead from the first set-piece of the game as Doherty hacked in the loose ball from close range.
Wolves dominated the ball with 72% possession in the first half but they showed a vulnerability from set-pieces as Shrewsbury drew level when Bolton headed into an empty net.
Sam Ricketts’ side then took the lead through Laurent who produced a hopeful shot from the edge of the box which Ruddy failed to hold onto as the ball trickled over the line.
The hosts lacked a cutting edge in attack and the front three of Helder Costa, Adama Traore and Cavaleiro struggled to find any rhythm.
Doherty – who has now scored more goals in all competitions than any other Premier League defender this season (5) – handed Wolves’ forwards a lifeline just before the interval with a header at the back post, as Shrews goalkeeper Steve Arnold failed to claim Jonny’s cross.
The 28,844 supporters saw Cavaleiro find the winner in the second half, and the four-time winners will now travel to the South West buoyed by their travelling fans who appear to have an appetite for a cup run alongside their encouraging top-flight league campaign.
