Luke McCowan’s penalty sent Dundee back into the cinch Premiership top six and left Aberdeen facing a battle against the drop.

McCowan’s fourth goal in six games – and his eighth overall this season – earned Tony Docherty’s side a deserved 1-0 win at Dens Park.

The midfielder netted in the 66th minute following a lengthy VAR check which ultimately saw Jack MacKenzie penalised for handball.

The home side had dominated the first half but some hesitancy in front of goal, good goalkeeping from Kelle Roos and some poor deliveries from corners kept the scores blank at half-time.

Aberdeen were led into the game by first-team coach Peter Leven, who was back in caretaker charge for the second time in six weeks following the end of Neil Warnock’s brief spell at the helm.

But the Dons have now gone 11 league games without victory and the defeat leaves them just three points clear of the danger zone following second-bottom Ross County’s stoppage-time equaliser against Hibernian, which allowed Dundee to jump above the Edinburgh side.

Any slim hopes of a top-six push vanished completely as results on the night left the Dons nine points behind Dundee with four games until the split.

They face another away game on Saturday, against Motherwell, before the anticipated appointment of a long-term successor to Barry Robson during the international break, although the visiting fans clearly had little faith in the decision-makers as they chanted “sack the board” in the closing minutes.

Dundee had Owen Dodgson back in the team after Owen Beck failed a fitness test while Leven named the same team that started in Warnock’s final game, a Scottish Gas Scottish Cup win over Kilmarnock.

The home side were quickly on the front foot and Curtis Main should have converted the rebound after Roos parried Scott Tiffoney’s strike. The former Dons striker took a touch and the goalkeeper smothered.

A brilliant Dodgson cross was just too far in front of Main six yards out before Dundee had a penalty claim for handball when Connor Barron blocked Tiffoney’s shot. Referee Steven McLean delayed and then gave a free-kick to Aberdeen inside the box.

Dundee remained well on top. Roos bravely denied Lyall Cameron as the midfielder slid in to meet Main’s low cross and the Dutchman tipped over Dodgson’s long-range striker.

Angus MacDonald blocked well from Tiffoney and Cameron shot just wide as Dundee continued to probe.

Aberdeen looked slightly better at the start of the second half but they fell behind after initially surviving a free-kick into the box.

McLean kept the 8,215 crowd waiting even after going to his monitor but he eventually pointed to the spot and McCowan sent Roos the wrong way.

Cameron soon had a great chance to double the lead but he dragged a shot wide following Tiffoney’s square ball.

Dundee continued to create chances and Roos saved from Cameron and Main.

There was plenty of effort from the visitors but home goalkeeper Jon McCracken remained untested other than from aerial balls until he held two headers from substitute Ester Sokler in the closing stages.

Aberdeen remain at risk of being drawn into a cinch Premiership relegation battle after the toothless Dons sank to defeat against St Johnstone.

Nicky Clark’s penalty late in the first half opened the scoring and Benjamin Kimpioka netted a second 13 minutes from time.

The win moves Craig Levein’s Saints level on points with the Dons as the two sides seemingly head on opposite trajectories.

Both sides rang the changes after weekend defeats, Aberdeen showing four changes after their 2-0 defeat to Kilmarnock, while Levein brought in five fresh players after defeat to St Mirren.

Neither side fashioned a clear view on goal in the opening period before a Matt Smith cross after 17 minutes found the experienced Clark, who tried to chest the ball home from close range, Kelle Roos saving comfortably.

Aberdeen were finding it hard to provide any service for lone striker Bojan Miovski and their best opportunities in the first half came from midfielders, Jamie McGrath forcing a fingertip save from Dimitar Mitov from a 25-yard free-kick, while Graeme Shinnie saw a shot from distance blocked by Liam Gordon.

The visitors were also shot-shy but they took the lead two minutes from the interval when Clark found the bottom left corner from the penalty spot after Richard Jensen’s handball.

The home side finally worked an opening for Miovski immediately afterwards but his subtle flick was easy for Mitov to hold.

A change of system at the interval saw Aberdeen become a more regular threat and Leighton Clarkson really should have levelled when he ran onto Roos’ long clearance but shot straight at Mitov.

Jonny Hayes flashed an effort wide and Clarkson hit over as the Dons searched for a leveller but the biggest threat to Levein’s side would be their own goalkeeper.

Mitov dropped a Connor Barron corner he looked to have full control of and his defenders scrambled to partially clear the ball before Miovski’s eventual shot was deflected over.

Two minutes later there was another scramble in front of goal, Mitov this time doing well to hold Stefan Gartenmann’s powerful header.

While Aberdeen may have had the volume of chances, the visitors looked sharp on the break with Kimpioka having the run of Gartenmann in particular and that would lead to the second goal.

Diallang Jaiyesimi’s ball over the top gave the striker something to chase and he drew Roos off his line before clipping home an angled shot to double his side’s lead.

Aberdeen huffed and puffed but as shouts of “sack the board” echoed round a rapidly emptying Pittodrie, Mitov in truth was rarely troubled.

Rangers moved level on points with cinch Premiership leaders Celtic as Neil Warnock’s first game as Aberdeen boss ended with a 2-1 defeat at Ibrox.

The 75-year-old’s appointment until the end of the season had captured interest UK-wide but, in a turbo-charged start to the game by the home side, winger Rabbi Matondo capitalised on a mistake by Dons keeper Kelle Roos to give Gers the lead.

However, Dons striker Bojan Miovski levelled as the first-half entered three added minutes with his 20th goal of the season.

Rangers piled on the pressure in the second half and in the 73rd minute, when Roos palmed away a Tom Lawrence thunderbolt, Todd Cantwell followed up to finish it off.

Rangers second-half substitute Dujon Sterling was shown a straight red card by referee Don Robertson in the 88th minute for a tackle on Jack MacKenzie – the official stuck with his decision despite the VAR asking him to check his pitchside monitor – and the 10-man home side played out eight added minutes before victory was confirmed.

Rangers and Celtic are now on 58 points with the Hoops boasting a superior goal difference of just one.

Celtic play at Hibernian on Wednesday, which will again leave the Light Blues with a game in hand as the title race heats up further.

Gers boss Philippe Clement brought in John Souttar, Ridvan Yilmaz, Lawrence and Cyriel Dessers with Mohamed Diomande, the 22-year-old midfielder signed on a loan from Nordsjaelland with an obligation for the Light Blues to buy, on the bench.

Warnock’s first team selection showed two changes from the side which started in the draw against Celtic at weekend with Jonny Hayes and Leighton Clarkson in for Dante Polvara and Killian Phillips.

The home supporters were up for the game and soon had something to cheer with a goal initiated by Matondo’s pass to Cantwell.

The Gers player moved the ball on to winger Ross McCausland whose low drive from the edge of the box seemed to lack real power to trouble Roos but he spilled the shot to the on-rushing Matondo who blasted it into the net from close range.

It was mostly all Rangers.

Matondo hesitated before getting a shot away after he had carved open the Aberdeen defence and his effort was blocked for a corner which Lawrence headed over.

Rangers appeared in control but when midfielder Connor Barron lobbed the ball forward it caught the Light Blues napping and Miovski fended off defender Connor Goldson and slipped the ball past Butland with assurance.

The goal turned the Ibrox crowd into critics and there was a different feel to the start of the second half.

Roos made saves from Matondo and Dessers but the flag was up for offside. That was enough for Clement.

Matondo made way for new boy Oscar Cortes, the Colombian winger on loan from Lens, with Fabio Silva replacing Dessers.

Aberdeen were pinned back in their own half but a well-organised and determined defence kept an increasingly frantic Rangers at bay.

The Dons repelled a series of corners with Roos blocking a Lawrence shot with his foot following one of Yilmaz’s deliveries.

However, Lawrence’s next effort from distance was venomous and although the Pittodrie keeper made a decent save, the ball fell to Cantwell who slid the ball back into the net for his fifth goal in eight games.

Amid more substitutions, Diomande replaced Cantwell in the 85th minute to make his debut and took part in a frantic finale where Sterling, on for Lawrence, was dismissed with referee Robertson asked to check his pitchside monitor by the VAR only to stick to his guns.

It was quite an introduction to Scottish football for Warnock but Rangers continue their chase of Celtic.

Aberdeen boss Barry Robson remained in bullish mood after a 1-1 cinch Premiership draw with Dundee saw the pressure on his position ramped up further.

Chants of “We want Robson out” were among the cleaner of those heard around Pittodrie at the end of another disappointing performance, though the clouds briefly cleared after Bojan Miovski converted a first-half spot-kick.

Ester Sokler saw a second goal ruled out five minutes after the interval but from consecutive corners, Lee Ashcroft was first denied by Kelle Roos before then turning home from a second delivery.

The result leaves Aberdeen in eighth place, while Dundee move ahead of Hibs into sixth.

And Robson said: “I thought we looked a bit leggy in the game – it’s the fourth game in 10 days.

“As well as the penalty, if Graeme [Shinnie] had scored then I think we’d have been in a great position to be 2-0 up, and Jamie McGrath misses a great chance to score early in the second half.

“I don’t think we were really good, but I thought we were alright and had enough in the game to win it.

“The fans were applauding when I came and some of them will sing these kind of songs, which is OK. I accept that and I signed up for the job.

“All I can focus on is coming in tomorrow and try to make us better and try to win the next game”.

Dundee boss Tony Docherty, the former Aberdeen assistant manager, admitted his greed after saying he was disappointed to only take a point from the match.

With eight men out for the game, his squad was boosted by the return of defender Owen Beck on loan from Liverpool until the end of the season after a successful first half of the campaign and the youngster could have netted an injury-time winner.

Docherty said: “We’re back into the top six which is progress for us, I can’t credit the players any more.

“There’s a real good spirit and mentality. There’s a toughness that makes me proud as a manager.

“It’s important that we put in a good 45-minute performance tonight, but I’m looking for more. We need to make Dens Park a real difficult arena for anyone to visit.

“To go into that fixture tonight with eight men out and come away disappointed we’ve not won is testament to the players and shows where we are at the moment.”

Jamie McGrath hit a double as a 4-2 victory at Motherwell gave Aberdeen a much-needed morale boost ahead of the Viaplay Cup semi-finals.

McGrath scored in each half with Nicky Devlin and substitute Luis Lopes also on target as the Dons claimed their first win in five matches to send them to Hampden on a high when they face Hibernian on Saturday.

Motherwell conceded some sloppy goals and never troubled Aberdeen keeper Kelle Roos until substitute Theo Bair netted his first goal at Fir Park in the 79th minute.

Mika Biereth scored his third goal in three cinch Premiership appearances off the bench in stoppage time but the Steelmen have now taken just one point from six games.

Aberdeen manager Barry Robson had taken responsibility for Sunday’s 2-0 defeat at Kilmarnock, admitting he should have made more than one change to his starting line-up. He made two at Fir Park as Dante Polvara and Leighton Clarkson came in.

Motherwell had Lennon Miller back from suspension while Conor Wilkinson made his first start since August.

Both sides had some decent spells of possession without threatening, until some hesitant defending gifted the visitors the lead in the 26th minute.

Dan Casey failed to get a decent connection on his header following Devlin’s cross and Paul McGinn was slow to react as McGrath got in behind to nod home at the far post.

The goal seemed to have a major and contrasting impact on each team. Aberdeen looked increasingly confident on the ball while Motherwell were struggling to string two passes together and the crowd started to get on their backs.

A slack pass from McGinn set up Polvara to shoot straight at Liam Kelly before the away team doubled their lead in the 44th minute.

McGrath’s pass put Bojan Miovski through and, although McGinn made a last-ditch tackle, Devlin was by far the quickest to follow up and slotted home.

Motherwell manager Stuart Kettlewell made two half-time changes, bringing on Biereth and Calum Butcher, who was making his first appearance since suffering a foot injury in May.

The start of the second half was delayed by about seven minutes by a technical issue with the VAR equipment.

The home fans soon lost their patience with referee Colin Steven as he booked four of their players in the space of eight minutes and waved away several appeals for Motherwell free-kicks – Biereth’s yellow card came for a show of dissent.

McGrath had a header saved before adding to his tally in the 68th minute after another goal-saving challenge fell for the Dons.

Casey this time slid in to nick the ball off Miovski’s feet and McGrath emerged with it as Kelly hesitated to pick up, before the Irishman found the net. The goalkeeper was booked for dissent as he claimed for an infringement.

Kelly was well beaten six minutes later when he came for Ryan Duncan’s corner as Lopes headed into the empty net.

Bair soon curled the ball home from 22 yards with Roos slow to get down at his near post.

The Canadian missed a decent chance from Biereth’s driven cross before the Dane slotted home following a cross.
