That's all from us tonight, but remember to watch those highlights on Sportscene currently showing on BBC One Scotland, iPlayer and here on the BBC website.

Catch up with Andrew Petrie's match report as Hearts go six points clear at the top of the Premiership with a 2-0 win over St Mirren.

And Thomas Duncan's report as Celtic survive a tough challenge to beat Falkirk 1-0 to move above Rangers on goal difference into second.

Earlier, Sporting Kansas City conceded defeat to Hearts in their pursuit of Rogers Mato despite the Uganda forward's current club, Vardar, claiming they had accepted an £870,000 offer, external from the Major League Soccer club for the 22-year-old.

Join us for live Scottish Cup action this weekend.

St Mirren manager Stephen Robinson tells BBC Scotland: "First half, Hearts go down to 10 men. Thought we played really well, scored two goals that were disallowed.

"And then we stopped doing basics. The two goals are woeful decisions. I look back on the last four games and we've had nearly eight goals now, not doing second phase properly against Rangers. The Motherwell goals, incredible decisions. Really poor decisions last week against Falkirk. And they're inexplicable at the moment.

"All the coaching in the world, you have to step up and make the right decisions.

"Hearts were the epitome of doing the basics right. When they needed to clear it, they cleared it. When they needed to defend, they defended as a team. And they were clinical on the top end of the pitch, where chances were we absolutely gifted them. They didn't work for them.

"And that's been the story of our season."

Next up in the league, it is the big one on Sunday, 25 January, when Hearts, without the suspended Beni Baningime, host Celtic.

On the same day, Rangers host Dundee and will look to take advantage of any slip-ups from the top two.

The title race is set aside for a week this weekend, with all four Premiership sides involved tonight starting their Scottish Cup campaigns in the fourth round.

St Mirren visit Livingston (15:00) before Hearts host Falkirk on Saturday (20:00).

Meanwhile, Celtic play sixth-tier side Auchinleck Talbot at Kilmarnock's Rugby Park on Sunday (17:30).

It is a big place of work for Stephen Robinson to pick St Mirren up.

I expected more when Beni Baningime was sent off. I thought it would give them a lift.

Players are not playing the passes that are going to penetrate teams and that shows they are lacking confidence.

It is not the St Mirren we know and certainly not the one that lifted the League Cup.

Neil [McCann] and Billy [Dodds] will give Kilmarnock a lift and, if Livingston start picking up points, St Mirren might be in a real battle to stay in this league.

Hearts head coach Derek McInnes tells BBC Scotland: "We were in trouble. We've got the experience of Sunday and we played similar.

"We tried to still carry a threat with three at the top of the pitch, give us a bit of oxygen and belief. Lawrence [Shankland], Claudio [Braga] and Kyzi [Kyziridis] carried the fight for us and gave us good moments without scoring.

"We reorganised at half time and St Mirren never made any changes, so the message was clear - 'this can be done'."

As for the red card, he adds: "Beni [Baningime] is the most popular boy in the dressing room, he was in tears and we had to get him out of trouble. We had enough encouragement, good breaks and the goal we score is a great bit of play.

"Our captain sets the tone, scores the goal and we have something to hang on to."

Lawrence Shankland is a brilliant story.

He is the hardest working, he is the most professional and he will be carrying that message into the dressing room.

On top of the being goalkscorer, he is a great captain.

There is confidence growing in that squad.

Hearts captain Lawrence Shankland says winning with 10 men on Sunday game his side belief they could do it again.

"It's a great result," the striker tells BBC Scotland. "The circumstances go against us again with the red card. It's not like Beni, he's not a ferocious tackler.

"The other night, we went so long with 10 men that it gave us the belief that we could do it. We still carried a threat at the other end and it was important we did that.

"It's everybody, not just the defence. To get results like that, everybody needs to dig in and defend as a team. Our distances had to be good, and we managed to get our goals as well.

"St Mirren would say themselves, they're not in the best moment. It was about us trying to impose that on the game.

"Good results always bring belief for a team. We want to stay at the top and that's where we are. We're just enjoying it."

Celtic manager Martin O'Neill was asked about adding players to the squad this month.

"We're hoping to do so," he tells BBC Scotland. "That's pretty necessary. We're making progress on things and certainly, by the end of the window, we should have some players to supplement this squad.

"There are reports about a lot of...I seem to get five or six per day. We are trying to make ground and we're doing pretty well I think.

"I thought my time was done here, so I wasn't expecting to pick up the pieces again and look at players.

"Just give us a little bit of time, cut me a little bit of slack and we'll be okay. The focus is to try to win some football matches, but the other aspect to it is to try to add to the squad if we can do.

"To add a bit of extra quality to help the players out here."

Falkirk manager John McGlynn is disappointed not to have at least taken a point from the game against the reigning champions.

"I think most neutrals will agree that we deserved to take something from the game - at least one point, maybe three points," he tells BBC Scotland.

"We had three good chances in the first half and, in the second half, Schmeichel makes a fantastic save.

"So I'm absolutely gutted for our players. They put so much into the game, they played particularly well.

"We have kept them quiet tonight. I have played Celtic before and the goalkeeper has been out best player, but that was not the case tonight."

Celtic manager Martin O'Neill is relieved to take the three points against Falkirk.

"It was on a knife edge," he tells BBC Scotland. "Falkirk had some good chances in the first half and on another night they might have scored.

"We were fortunate to go in 1-0 ahead at half time. We hadn't played particular well.

"I thought the second half we started to improve a bit and got a bit tighter.

"Overall, delighted to win, but we can play much better.

"It is only 72 hours since we played brilliantly against Dundee United."
