It was a tough test for Mick McCarthy's second string on Tuesday night against a spirited Southend side.
The visitors started the game on the front foot, scuppering a few good chances. Wolves were clearly finding it hard to get going.
But, just as you felt Southend might get a shock goal, they went behind; Nenad Milijas confidently burying a 27th minute penalty. The decision was stonewall - young debutant Sam Winnall showing great skill to get into the Shrimpers box, only to be felled by Chris Barker.
But the confidence the goal should have brought was non-existent. Bilel Mohsni was unfortunate not to pull the away side level almost immediately after the penalty with a weak header, and minutes later the same man had a goal disallowed for offside.
The Premier League side were in the lead, but looked like a side desperate for the half-time whistle.
Southend started the second half the way they ended the first, Barry Corr forcing Wayne Hennessey into a low save.
Slowly but surely Wolves were beginning to take a little more control of the game though, and started to fashion chances of their own; Winnall was slightly wasteful in front of goal, as were Milijas and Hemmings. But the signs were positive.
But again, Southend came back at them, Paul Sturrock's son Blair hammering a shot against the crossbar with 20 minutes remaining. McCarthy decided enough was enough and sent on Ebanks-Blake and Kevin Doyle to get the job done.
They had barely had a chance to effect the game when the equaliser was conceded - Craig Easton stooping to guide a low header past Hennessey.
Wolves could have had the tie sown up no more than two minutes later, if it hadn't been for the linesman's flag. Ebanks-Blake on the receiving end of a close decision.
As the game dragged on, it became scrappy; tired legs accounting for misplaced passes and mis-hit shots. Southend were the main culprits; wasting some great chances to snatch a famous victory.
Ebanks-Blake was once again ruled offside when he pounced on a deflected Milijas shot and the game looked destined for penalties. But, just before the final whistle sounded, stand-in captain Richard Stearman scrambled a Ronald Zubar cross over the line and guaranteed his side will be in the pot for the Third Round draw.
