Yuki Ohashi's headed goal deep into stoppage time snatched a vital three points for Blackburn in their fight for Championship survival as they beat Lancashire rivals Preston in Michael O'Neill's first home game as Rovers boss.

Japanese attacker Ohashi came off the bench to apply the winning touch from Eiran Cashin's deep cross in the last of five added minutes at Ewood Park, in a match that seemed destined to end goalless.

The victory gives Rovers a six-point cushion over the relegation places going into the rest of the weekend's games and means Sheffield Wednesday will be relegated to League One on Saturday if West Brom beat leaders Coventry.

Preston hit the woodwork twice through Alfie Devine but only registered three shots in the match and miss the chance to move back into the play-off spots.

In a game that lacked much of the bite and energy that so often lights up a local derby, Blackburn fans had to wait until the 95th minute for the one moment of real quality.

It came from a throw in, with the ball recycled back to Cashin out wide on the left at the second phase, with the defender sending in a deep cross.

Ohashi, one of the smallest players on the pitch, found himself in plenty of space to leap high and send a looping header back across goal and into the corner beyond Preston keeper David Cornell.

It sparked wild celebrations with O'Neill, taking charge of his first home game for the club, slipping over on the turf. He and his players knew what a huge moment it could be.

After a drab first half, it was Rovers who showed more attacking intent in the second, with Matias Jorgensen and Moussa Baradji going close for the hosts.

North End's attackers had a subdued evening, rarely testing Blackburn goalkeeper Balasz Toth, although they did strike the woodwork within two minutes of the start of the match.

Devine's deep corner evaded everyone and bounced up off the top of the crossbar and over, before Lewis Dobbin drew a rare save from Toth with a jinking run into the box and shot towards the near post.

Devine came within a whisker of opening the scoring directly from a set-piece again, this time whipping a dangerous free-kick into the area, which somehow squeezed all the way through and just kissed the post as it went behind for a goal-kick.

Paul Heckingbottom's side enjoyed a brief period of dominance after the introduction of Thierry Small just before the hour but ultimately missed a chance to strengthen their play-off credentials.

Having sat sixth on 94 minutes, they could find themselves as low as 12th in a congested Championship table if results go against them on Saturday.

Blackburn Rovers boss Michael O'Neill told BBC Radio Lancashire:

"I'd have loved us to play scintillating football and be 3-0 up at half-time but it was never going to be that kind of game.

"We had to dig deep and I thought [in the] second half we shaded the game, I thought probably Preston shaded the first half.

"[In the] Second half I thought we did a lot of good things. We had other opportunities we possibly could have done a little better with.

"The game did look like it was going to drift to a 0-0, but that's why you dig in and you keep doing what you do, and obviously Yuki comes up with a fantastic header and it's a great way to win the game."

Preston North End boss Paul Heckingbottom told BBC Radio Lancashire:

"Angry's the real emotion, I think. We should have took a point there. The nature of that and it's anger.

"I can take losing [but] I'm very disappointed. The game itself, we sort of knew Michael [O'Neill] would go with the five at the back, he changed it [in the] second half, and we picked a team we knew would play well against that.

"I felt we had control of the game in spells but without looking the threat we wanted to do.

"We might have territory, we might have had set plays, we might have had moments where we controlled the ball but not enough chances at the end of that.

"I'd have taken a point; us not at our best attacking-wise, a clean sheet away from home and a point is never to be sniffed at in the Championship."
