After a horrendous start to 2016, St Johnstone are unbeaten in their past three games, hammering Hearts 3-0 at Tynecastle in their last outing. Bottom club Dundee United sit seven points behind Kilmarnock, with a game in hand, and have won three of their past five league fixtures as they battle to retain their top-flight status.

"Huge prize up for grabs as Ross County visit Dundee. County currently in 6th place but only three points clear of their hosts. Paul Hartley looking for his players to replicate their achievements of last season and force their way into the top half of the league for the run-in.

"Both sides have injuries and suspensions to key players with Harkins and Bain missing for Dundee with the influential Jackson Irvine failing to recover for Jim McIntyre's side.

"The previous two matches have produced 13 goals this season and this should be an open style type of game with so much at stake for both clubs."

A potentially momentous day in Kirkcaldy as Rangers have the chance to secure the Championship title and promotion to the Premiership. They need to win and hope Hibernian drop points against St Mirren, otherwise they'll have to wait until Tuesday night at Ibrox when they play Dumbarton.

"Greg Tansey is suspended so John Hughes brings in Andrea Mbuyi-Mutombo as the one change from the team that beat local rivals Ross County last time out.

It's also just one change to the Motherwell line-up that beat Aberdeen a fortnight ago with captain Keith Lasley returning at the expense of Jack Leith."

What a game. Jamie Walker gives Hearts an early lead but a Patrick Roberts-inspired comeback sees Celtic extend their lead at the top of the table to seven points ahead of Aberdeen facing Hamilton tomorrow.

Hearts' misery is compounded by being reduced to 10 men. Defender Juwon Oshaniwa receives his marching orders for a second bookable offence. A sliding challenge on Nir Bitton draws the ire of referee Bobby Madden, but it looked harsh! 

Four minutes of added time remaining with Celtic poised to move seven points clear of Aberdeen in the title race.

Hearts denied a late goal as Craig Gordon brilliantly tips away Dauda's bullet header from Liam Smith's cross.

Celtic substitute Callum McGregor is denied by a superb diving Neil Alexander as the hosts search for a fourth goal. Hearts continue to look dangerous on the counter attack but Celtic remain a threat to add to their tally. 

It's not Leigh Griffiths' day. The striker brilliantly chests down a pass on the edge of the area but sees his goalbound effort blocked by some frantic Hearts defending.

It's the striker's last action of the day as he then gallops off to be replaced by the tattooed Colin Kazim-Richards.

The story of Hearts' problems this afternoon is illustrated by a free kick from Juwon Oshaniwa whipped into the Celtic box and Juanma heads straight at Craig Gordon from close range.

An ashen-faced Robbie Neilson looks on...

 Celtic come roaring forward through Nir Bitton and the Israeli midfielder feeds Patrick Roberts who in turn finds Leigh Griffiths. But the striker pays dearly for a poor first touch and Hearts clear their lines. 

Ronny Deila shuffles his Celtic pack: Callum McGregor trots on to replace the crimson-cheeked Gary Mackay-Steven.
