Terry Devlin denied Wolves victory just as the hosts' inspired substitutions again looked to prove decisive as Portsmouth drew 1-1 at Molineux in the Championship.
Four days after Tawanda Chirewa came off the bench to score the winner at Burnley, substitute Jordan James' strike looked like it would prove the difference for Wolves.
But right-back Devlin popped up with a superbly taken equaliser to give Pompey an unlikely share of the spoils.
The scoreline was harsh on Wolves as Chirewa hit the bar and was denied another goal, while Mateus Mane and Fer Lopez missed chances in a dominant second-half performance. Portsmouth failed to hit the target until Devlin struck in the 86th minute.
In a forgettable first half, Andre had the only Wolves chance. The Brazil midfielder lofted a bouncing shot just wide from 25 yards after Devlin beat Marshall Munetsi to head away Mane's cross.
Portsmouth's only chance of the opening half came in the 36th minute. Wolves failed to deal with Adrian Segecic's deep free-kick and after Nasser Djiga missed the header and Ebou Adams' angled effort was blocked, Rocco Shein's low shot was a few feet wide.
Wolves made a double change at half-time to spark some life into the game - Chirewa, Friday's matchwinner at Burnley, and James replaced Sean Neave and Munetsi - and it worked, with a much-improved display.
Chirewa, who scored the winner within 21 seconds of his arrival at Turf Moor, quickly rattled the bar with a tight-angled, rising shot after turning inside his man.
Mane dragged a low, angled drive well wide, then Lopez volleyed wide from Rafiki Said's inviting cross as Wolves continued to probe for the breakthrough.
That came in the 62nd minute from James, who slammed home a fierce low first-time drive after starting the move with a one-two with Lopez, beating Nicolas Schmid at his near post.
Pompey missed a good chance to equalise when Adams headed over substitute Marezi's corner from five yards while substitute Tommy Doyle's teasing cross just missed the sliding Chirewa as Wolves sniffed a second goal.
But Devlin struck when he chested down and volleyed right into the corner of the net after Marezi's free-kick had been headed clear.
Chirewa's low shot was clawed around a post by Schmid as Wolves desperately pushed for a winner at the death and both benches had to be pulled apart at the final whistle as tensions briefly boiled over before order was quickly restored.
Wolves' Cesar Peixoto:
"I think the players, because of the last games, were a little more anxious and played more secure. They didn't find the right courage to play in the first 45 minutes.
"At half-time I told them to play with more courage, with more mobility. We made two substitutions and I think we were better.
"In the last few minutes we conceded a goal from their first shot on goal. I think it is an unfair result but we have to do better in the first 45 minutes.
"I said at half-time, go and run, play free, play with courage and be brave in the game. But in the last few minutes we dropped deep because the players wanted so much to win the game to take off this pressure."
Portsmouth's John Mousinho:
"I thought it was about right. Wolves had more possession and shots and the onus is on them as a club coming down from the Premier League to do that.
"But overall we did a really good job of restricting that and when you take everything into consideration I thought we deserved it."
Mousinho played down the angry scenes between the two benches at the final whistle.
He added: "I shook their manager's hand and he said I talk too much and I said that's what I do as a head coach.
"It was handbags and I walked off - it's fine, no worries."
