That's all from us on another topsy turvy day in the Scottish Premiership - and the conclusion of the main season in Leagues 1 and 2.

However, our feast of football continues with Sportscene's Premiership highlights show kicking off at 19:15 BST on the BBC Scotland channel, which is repeated at 23:40 on BBC One Scotland.

Tomorrow, attention turns to the Old Firm derby, with kick-off between Rangers and Celtic at high noon at Ibrox.

Only pride and city bragging rights are at stake for both the visiting champions and hosts already secure in second.

Meantime, in the battle for third, Hibs have the advantage but must visit Celtic next weekend as Dundee United host St Mirren and Aberdeen travel to face Rangers.

There could be more twists and turns to come in the race for those European qualification places.

Dundee manager Tony Docherty tells BBC Scotland: "I'm really, really angry and really frustrated. And most of that is directed towards the officials.

"We’re finding a way in this country with our officials to disallow goals. We're looking for reasons to disallow goals.

"I will not abdicate responsibility as Dundee manager - I will take full responsibility for my team contriving to lose that game. But, if we go in at half-time like we should, justifiably, 2-0 up, the dynamic of the game is totally different.

"If we brush this under the carpet again and don’t address it then it’s a disgrace.

"Tony Portales scores a brilliant goal with his right foot and an even better one with his left foot. And the officials contrive to disallow that goal – something to do with Clark Robertson being in an offside position. Does he affect anything to do with that strike into the top corner?

"The officials are killing the game."

St Mirren manager Stephen Robinson tells BBC Scotland: "We struggled at the start. I thought Aberdeen started really well, we just couldn't get into a rhythm or get hold of the ball.

"When the goal was disallowed, it gave us a bit of a kickstart. I don't remember too many clearcut chances from Aberdeen. I thought we dealt with their threat well.

"We can play better than what we did today, but it shows the character of the players and the quality when we've needed it. It was a great finish from Mika [Mandron] - a set play we've worked on tirelessly."

Hibernian head coach David Gray tells BBC Scotland: "The result was the most important thing - the reaction from the players to the defeat last weekend.

"Everyone was looking to see how this Hibs team would bounce back and I got that today.

"Credit to Dundee United in the second half, they got a bit of a foothold in the game and we lose a really poor goal.

"The players showed me massive character to make sure we saw the game out. It was a massive team performance."

Today's results set up a massive game at McDiarmid Park next Saturday.

St Johnstone host Ross County in a battle of the bottom two and anything less than a win will surely end the Perth side's hopes of avoiding automatic relegation.

Third-bottom Dundee visit Kilmarnock, who are now four points ahead and would end their own relegation fears with a victory.

Aberdeen manager Jimmy Thelin tells BBC Scotland: "We wanted more.

"The game was what we expected. We were not good enough to deserve to win, but maybe we were not bad enough to lose. It was a classic 0-0 game, but they used the opportunity from the set play to score that goal.

"The final pass today didn't arrive in the right spaces - that's football sometimes. Today was not the perfect game, but also St Mirren did things well.

"We need to improve some parts in the away games and do better because we now have three more important games in the league.

"We have to believe and try to do some things better in our away games."

Motherwell manager Michael Wimmer tells BBC Scotland: "I'm very happy, very proud of the guys.

"They did well, especially in the second half - and the first half, we lacked a little bit of energy and also the defence from the two throw-ins was not good enough.

"We spoke about this at half-time, but the second half was brilliant with certain shots on goal and also after the red card there was no feeling that we could not win the game."

On John Koutroumbis' sending off, Wimmer added: "To be honest, during the game, I thought, no, I thought this was a wrong decision and now I saw the first pictures, the first clips on television and so I have to say it's okay, you can give the red card.

"We spoke about what we were doing for the red card and I felt the whole bench, I felt the whole players on the pitch, no worries, we do this together."

St Johnstone manager Simo Valakari tells BBC Scotland: "The fight continues. Other results give us a little lifeline and that's what we need to grab.

"We could not perform well enough today. We knew, against Kilmarnock, if you go 1-0 down, it will be difficult and I'm very disappointed in how we give away the first goal.

"We are very honest with ourselves - it was not good enough how we defended in crucial moments. It doesn't matter who you play, you need to be better with that.

"Disappointment, everyone is down, but we need to pick ourselves up. We have these three matches to grab something. No time to feel sorry for ourselves. It's hard to pick yourself up, but we need to do it."

East Kilbride completed their passage into the Pyramid Play-off final after sharing a six-goal thriller with Brora.

The Lowland League champions' 4-1 first-leg win proved crucial against their Highland counterparts and they will face Bonnyrigg, who finished bottom of League 2, for a place in the SPFL next season.

Ross County manager Don Cowie tells BBC Scotland: "We get the first goal, it's important we keep it at 1-0 going in to half-time.

"We concede, the game is still in the balance, concede a poor second, but we are still in the game - then we make a mistake and are punished.

"It's fine margins. Ronan has a great opportunity at 1-1 and doesn't take it.

"There is no point feeling sorry for ourselves, we have to get ready for a massive week next week.

"I've got belief in the group and myself, but we've got to get act upon it."

Kilmarnock manager Derek McInnes tells BBC Scotland: "The pitch is really difficult. People slag our pitch, but that is really difficult for the players to try and connect.

"We tried to play the conditions, take the anxiety out of it. We could have been more effective with our work, but we got a brilliant first goal. We saw the importance of another midfielder arriving late in the box.

"Davie [Watson] has the quality to get on the road, a brilliant finish from the wee fella. We were good in the game, in terms of being quite calm. But we gave them too much encouragement. Too many balls were coming into our box, so we made a change at half time.

"We knew the second goal didn't need to come, but ultimately you still want it. We were able to breathe easy, it put pressure on them and we stayed strong within our structure. It was a very mature, professional performance and the exact one that was needed.

"It doesn't need to be dramatic, we don't need to be brilliant, we just need to be steady with our work."

The League 1 play-off semi-final line-ups have been decided, with Edinburgh clinching third place despite losing their derby with Spartans.

That's because fourth-top Elgin also lost - to runners-up East Fife.

It means the Fifers will take on Edinburgh while Elgin face Annan, who finished second bottom in the league above.

At the bottom, Bonnyrigg fall agonisingly short in their bid to avoid the Pyramid play-off to stay in League 2. A victory away to Stranraer was not enough as Forfar's draw with Stirling keeps the Angus side ahead on goal difference.

• Clyde 6-1 Peterhead
• East Fife 2-0 Elgin City
• Forfar Athletic 0-0 Stirling Albion
• Spartans 3-1 Edinburgh City
• Stranraer 0-1 Bonnyrigg Rose

Interim Hearts head coach Liam Fox tells BBC Scotland: "We are delighted after a difficult week for the club.

"We had to fight through a period where we lost our way but stuck to what they were asked to do. That shows the players' courage and we scored three really good goals.

"There's natural disappointment when County scored, but we were asking them to be brave and pass the ball and, in moments like this, that can be difficult, but I am delighted with the response.

"We did a lot of work this week on the structure of the team and how we want to create chances. Lawrence Shankland will score goals wherever he plays, I just felt we need him in and around the box to hopefully get him the chances he did today, because when he gets those, he usually hits the back of the net."

Asked if Fox expects to be in charge against Motherwell next weekend, Fox replies: "Unless I hear otherwise, yes, I do."

The Championship play-off semi-final line-up are complete, with Cove Rangers, Queen of the South and Stenhousemuir sealing their places.

Cove finish second after a convincing win over Annan and will face Queen of the South, who finish third after drawing with champions Arbroath.

Stenhousemuir leapfrog Alloa Athletic, who lost to Kelty Hearts, into fourth after a win over Dumbarton and will face Airdrieonians, who finished second bottom of the Championship.

• Annan Athletic 2-4 Cove Rangers
• Arbroath 1-1 Queen of the South
• Kelty Hearts 2-1 Alloa Athletic
• Montrose 0-2 Inverness Caledonian Thistle
• Stenhousemuir 2-1 Dumbarton

Hibs started the day in pole position to finish third, albeit only on goal difference, and they end it with a three-point gap between themselves and Aberdeen - and six clear of Dundee United.

Stay with us for manager reaction from around the Premiership...

There's still three games to go, but it looks like this afternoon has shaken down the potential.

The genesis being wins for Motherwell, Hearts and Kilmarnock.

Well are definitely arithmetically safe, Hearts and Kilmarnock have healthy cushions.

St Johnstone, six points adrift at the foot, look doomed to automatic relegation, with Dundee and Ross County in a head-to-head to avoid the play-off spot.

A sensational second-half fightback from 10-man Motherwell and Michael Wimmer's side secure their Premiership safety.

After a largely dominant first 45 from Dundee in which Antonio Portales' scored two beautiful volleys - albeit one ruled offside - Motherwell came out fighting in the second half and Tom Sparrow rifled the ball into the roof of the net to draw them level.

They kept battling after Koutroumbis was shown a red card for a challenge on Ziyad Larkeche and Tawanda Maswanhise's late header sealed all three points.

Dundee, though, are just two points off second bottom Ross County.

It's another excellent outcome for St Mirren who are loving life in the top six once again, safe from danger with aspirations still to chase.

It's unlikely Mikael Mandron's winner will deliver a European place given they have to overall an eight-point deficit to Aberdeen in three games.

That said, it's not impossible and the chase for fifth is now on with Dundee United next up. Only five points separate those sides.

This is a significant blow for Aberdeen. They will point to Jeppe Okkels' strike being ruled out for an earlier handball. It's debatable, but overall they didn't do enough, particularly after falling behind.
