Tony Pulis' side looked much more comfortable before a chaotic end to the game, which played into the hands of the hosts' quick attackers.

But Rovers could not find a winner and are now five points off the top six. The Owls are three points adrift in the bottom three but ended a run of three successive away defeats.

Rovers made one change from the defeat at Stoke, replacing Tom Trybull with Daniel Ayala, while Pulis made two alterations from the Owls' win against Coventry, handing starts to Moses Odubajo and Joost Van Aken.

The game quickly settled into its default pattern of Wednesday sitting back and inviting Rovers to break them down, which yielded a solitary tame Armstrong effort early on.

Despite enjoying the lion's share of possession, Blackburn could not fashion anything meaningful and fell behind to a strike of real quality four minutes before half-time.

It came from nothing, as Barry Douglas' headed clearance hit Ayala and fell to Reach 30 yards out. He had plenty to do but measured a beautiful left-foot strike into the top-left corner for his second goal this season.

Another defensive lapse just after the break presented Windass with another opportunity but his initial effort was blocked and then his shot on the turn went wide.

Wednesday grew in confidence and should perhaps have extended their lead when Barry Bannan combined with Reach but the latter dragged wide after pouncing on another Douglas error.

Rovers rang the changes and it gave them extra impetus. The width of a post denied Armstrong after a smart turn and shot but the hosts equalised 14 minutes from time thanks to a special goal by Rothwell.

He carried the ball 40 yards, surging past the Owls defence before calmly passing the ball beyond Keiren Westwood from 12 yards.

It opened the game up and Armstrong was denied at the end of a lightning counter-attack moments later, when Westwood parried his effort.

At the other end, Blackburn were almost caught cold with a quick free-kick but Ayala's heroic intervention deflected Windass' shot over.

Armstrong had another sight of goal towards the end but saw his shot deflected just wide, and Rovers will see it as two points dropped.
