Scottish Cup
FT: Livingston 2-1 Raith Rovers
A first win since 7 October for David Martindale’s men!
Jamie Brandon’s fine strike and Daniel MacKay’s terrific header sends injury-plagued Livingston into the next round of the Scottish Cup at the expense of Premiership promotion chasers Raith Rovers.
Rovers took an early lead through Jack Hamilton but failed to take their chances in the second half when the game was for the taking.
FT: Ross County 0-3 Partick Thistle
Kris Doolan's side got revenge against Ross County for last season's playoff final defeat with a comprehensive win over at Dingwall.
An largely even, end-to-end first half ended 2-0 to Thistle thans to Brian Graham and Scott Robinson getting on the end of tidy deliveries from Thistle's wide men.And nine minutes into the second half Stuart Bannigan blasted home a stunning volley to make it 3-0 and put the game beyond doubt.It was a solid performance for Thistle but Derek Adams will be left wondering why his misfiring side, which managed to match Thistle for the game, couldn't find the net.
FT: Kilmarnock 2-0 Dundee
Two goals inside two minutes for Kilmarnock take them into the last 16 of the Scottish Cup.
Derek McInnes gets the better of his former assistant Tony Docherty.
FT: St Mirren 1-0 Queen of the South
Alex Gogic's bullet header does the job for St Mirren, who edge past Queen of the South to reach the last 16 of the Scottish Cup.
FT: Airdrieonians 1-0 St Johnstone
It's over in Airdrie.
St Johnstone's miserable cup form continues with a defeat to the second-tier hosts.
FT: Forfar Athletic 0-1 Hibernian
Not the most convincing of performances, but job done for Hibs.
A really strong performance from League 2 Forfar, who will be wondering how they failed to score after racking up the chances.
Plenty of spirit to take into their rest of the campaign, while Nick Montgomery's side will need to kick it up a gear when they return to league action.
Angus Mailer
Late madness everywhere as fourth-tier Rose stun League 1 leaders Falkirk late on!
Adam Brooks
Four for the Highlanders.
Dan MacKay
A hugeeee goal for Livi!
Daniel MacKay rising highest in the box to head home beyond Kevin Dabrowski.
Cracking technique from the winger to put the hosts ahead.
Mark McKenzie
The hosts add a bit of gloss to it.
Airdrieonians 1-0 St Johnstone
Andy Considine is off target as time runs out for St Johnstone to force extra time.
Blair Spittal
Another peach from Blair Spittal, who curls in a fine free-kick.
He should be going home with the match ball.
St Mirren 1-0 Queen of the South
Greg Kiltie has the ball in the back of the net for the second time this afternoon.
But, just as in the first half, it's ruled out for offside.
Livingston 1-1 Raith Rovers
Kenny Crawford
BBC Sport Scotland at Almondvale
It was a surprise to see Dylan Easton on the bench for today’s match, but Raith’s talisman is on now in place of Kyle Turner so we’ll see if he can be a game-changer.
Motherwell 2-1 Alloa Athletic
Adam Montgomery almost scores on his Motherwell debut.
Twisting and turning, he wriggles free in the box and sends a shot inches over the crossbar.
He's been a bright spark on a dim day for the Fir Park faithful.
Airdrieonians 1-0 St Johnstone
Veteran forward Stevie May replaces Benjamin Kimpioka as St Johnstone chase an equaliser at Airdrieonians.
