Wolves welcomed Blackburn Rovers in what was their first game in the Championship since the end of the 2017/18 season.
The recently-relegated side were the favourites going into this and took the lead in the 18th minute when Fer López split the Rovers defence before Marshall Munetsi kept his cool to finish past Balázs Tóth.
However, Blackburn fought back and levelled the score in the 27th minute after Ryoya Morishita swung in a cross from the right that Sean McLoughlin nodded home.
The visitors then completed the turnaround shortly after the restart. Again it came from the right with Dapo Afolayan this time providing the ball that Andri Gudjohnsen converted from close range.
From that point on Wolves pushed to get back into the game, bringing on Raúl Jiménez with an hour gone after three seasons away from the club.
As time was running out the home side was awarded a penalty in stoppage time after Ryan Alebiosu was judged to have been inside his area when the ball struck hand. Inevitably, it was Jiménez who took the resulting spot-kick, sending Tóth the wrong way and making it 2-2 on the night in an entertaining opener to the new Championship season.
