Wednesday came from behind twice to emerge from Blackburn with a 2-2 draw.
Three of the goals came in a first half that Rovers edged, with Hope Akpan and Corry Evans scoring either side of Modou Sougou for the Owls.
Wednesday significantly upped the ante for the second period and finished with a flourish, with substitute Lucas Joao nodding a late equaliser to give the visitors a share of the spoils.
But back at the beginning of an eventful encounter, it was the worst possible start for the Owls when Rovers struck on just four minutes.
Craig Conway swung a curling corner into the mix for the advancing figure of Akpan to glance right into the centre of the goal.
Former Owls loanee Ben Marshall sent a long ranger wide moments after the restart and the hosts went on to ask more of the questions as the first half unfolded.
Try as they did, Wednesday struggled to make a real impression beyond the midfield area, with the Blackburn defence largely untroubled.
The same, though, was true of the Owls’ backline as something of a stalemate in terms of possession developed in driving rain at Ewood Park.
But on 39 minutes, and out of nowhere, Wednesday restored parity.
Atdhe Nuhiu flicked on for Kieran Lee, who slalomed his way past two defenders and goalkeeper Jason Steele only to hit the post from a tight angle.
But Sougou was in the right place at the right time to stab home the rebound to draw his side level.
Then, just as the Owls looked to build on that equaliser - Nuhiu struck narrowly over the crossbar - Rovers stole back into the lead a minute before the break, aided by a slice of good fortune.
Conway’s corner was cleared to the edge of the area and an Evans hit was looking harmless until a wicked deflection wrong-footed Keiren Westwood and the ball nestled into the opposite corner.
Carlos Carvalhal made a double substitution at the break, introducing Joao and Gary Hooper and from the resumption, Wednesday looked a threat.
Rovers survived a handball penalty shout before Fernando Forestieri drilled just wide from distance as the Owls had the bit between their teeth.
Forestieri delivered an audacious cross with the outside of his boot to the far post and Tom Lees was a whisker away from a connection, then Hooper stabbed agonisingly wide from close range.
But the feeling was that Wednesday would get something from the game, which rang true five minutes from time.
Lee scooped a high ball towards the edge of the six-yard box and Joao climbed to head Wednesday’s second equaliser.
