Motherwell with by far the brighter start in the second half, exploiting the wings to pepper the Hearts penalty box with crosses and corners.

Hearts have shifted formation to a back four but it seems to be giving Well more licence to get forward.

Half-time change for the visitors. Lewis Jamieson is on in place of James Scott.

And it's clearly made a difference as there's a very early chance for St Mirren.

Shamal George gets down to save the initial effort and Michael Nottingham, who's stood behind his keeper, is there to head the rebound away from the goalline.

Double half-time substitution for Hearts.

Off go Beni Baningime and Dexter Lembikisa, on come Kenneth Vargas and Nathan Atkinson

As I mentioned earlier, Luis Palma was getting no change whatsoever out of Lewis Mayo, the Killie right-back.

The Honduran has been hooked at half-time, with South Korean international Yang taking his place.

Celtic boss Brendan Rodgers has made a change at the break, with Yang Hyun-jun replacing Luis Palma on the wing.

And the home side immediately show a bit of nerves as goalkeeper Joe Hart needlessly punches away a cross to concede a corner, but the visitors can't take advantage.

We go again around the country.

What a whirlwind that first half was.

The Bairns blitzed into a three-goal lead through Calumn Morrison, Ross MacIver and Calvin Miller, which led to some Accies fans leaving the stadium after half an hour.

But Ahkeem Rose rounded Nicky Hogarth nicely to restore a little bit of hope for the visitors.

I wonder whether both managers might actually be reasonably happy as they quaff their half-time cuppas and order instructions from the second 45.

Celtic got the goal their play deserved, with Kyogo clinical and front-man Adam Idah impressing with his touch, control and link-up play.

Both goalkeepers have made terrific stops, Joe Hart from a flashing Liam Donnelly header from a corner and Will Dennis from a Matt O'Riley shot into the turf that bounced up.

Decent fare here, and at 1-0 it's still very clearly in the balance.

How big a moment is that for Livingston and their manager? With Ross County trailing this could be monumental with a trip to Ross County next up.

We've been crying out for quality here, or at least a decisive moment, and that one might prove so crucial in the relegation battle.

The home side really need to capitalise on home advantage and finally have something to build on, chasing just their third league win.

Just as it looked as though the half was going to finish all square, Tete Yengi comes up with the goods for the home side.

James Scott came closest for the visitors but he couldn't direct his close range effort on target.

Both sides created their fair share of chances but it's relegation-threatened Livingston who lead at the break.

A huge boost for David Martindale - can they keep it up in the second half?

Celtic are half way to going three points clear at the top of the Premiership and just about deserve it on the balance of play.

Kyogo Furuhashi's back-post header separates the sides, but Celtic were also thwarted by a couple of Will Dennis saves and a clearance off the line.

However, Kilmarnock also forced a save from Joe Hart and are still in this game.

Two teams playing nice football but lacking a cutting edge at Tynecastle.

Lennon Miller came closest to finding the net, put through clean on goal in the 36th minute with a beautiful pass by Harry Paton, but he rolled his finish wide of Zander Clark's goal.

Hearts have found much play down the flanks, but the Steelmen's back line has proven resolute in dealing with any crosses coming in.

Another poor start from Aberdeen, another comeback.

Martin Boyle gave the visitors the lead after 13 minutes, rounding Kelle Roos after a poor Aberdeen clearance, before Nicky Devlin got the Dons' equaliser after reacting quickest to a rebound.

A draw doesn't help either side. They'll both be desperate for a goal.

Scott Tiffoney's well-taken effort separates the teams at the break.

It's been an entertaining contest, with Lyall Cameron providing the bulk of the home chances, while Simon Murray drew a super stop from Trevor Carson up the other end.

Both teams stringing together some neat attacking play despite torrential rain.

Tiffoney's cool strike, after being played through by Dara Costelloe, is the difference.

So close to a second for Celtic.

Matt O'Riley's first shot on the turn is beaten away by goalkeeper Will Dennis and the midfielder's header on the rebound is cleared off the line by Corrie Ndaba.
