Benjamin Nygren and Anthony Ralston are on for Celtic, replacing Jahmai Simpson-Pusey and Luke McCowan.

Simpson-Pusey has impressed in his Celtic debut as a makeshift right-back but made a wild challenge a few moments ago.

Motherwell manager Jens Berthel Askou tells BBC Scotland: "It was probably the performance of the three [games against Aberdeen this season] where we were most dominant, in most control, throughout the game.

"We lacked a little bit of sharpness to convert the dominance into open, clear-cut chances and that's the most disappointing thing, because the performance was really solid.

"Many things to be happy about, but we'll have to keep building and progressing our attacking game so we win games like this.

"We probably got a little over-confident, being too clever or too smart."

I wondered how Celtic would be today with all the injuries.

But they have made a lot of changes and I think it's actually improved them.

David Watson plays a lovely pass over the top for Scott Tiffoney, but the Kilmarnock winger hesitates and Auston Trusty gets back for Celtic before racing up the line and leaving a couple of opponents in his wake.

Maybe Martin O'Neill should play the big centre-half on the wing!

Hearts stay the only unbeaten in the league this season, but they fall short of the 32 points from the opening 12 league games achieved under George Burley at the start of the 2005-06 season.

No other non-Old Firm side had matched that since and that now remains the case after their 1-1 draw with United.

At least Derek McInnes knows the current owners will not follow the example of Vladimir Romanov by sacking the manager when in such a healthy position.

Celtic midfielder Luke McCowan, who appears to have changed into a short-sleeved shirt at half-time, whips is a corner to the back post, where Daizen Maeda heads over the top.

Are Celtic on their way to narrowing that gap at the top?

Halfway there.

As it stands, Hearts have moved 10 points clear of Celtic at the top of the Premiership.

But their failure to beat Dundee United, combined with Celtic leading at home to Kilmarnock at half-time, means the lead looks likely to be cut to seven by the end of the day.

Meanwhile, Rangers' win in Dundee means Danny Rohl's side have moved to within 12 points of Hearts while they and Celtic both have a game in hand.

Rangers nudge up to fourth place after a comfortable victory at Dens Park.

Nicolas Raskin and Mikey Moore got the early goals and Djeidi Gassama added a late third.

Dundee stay second bottom.

What a breathless second half. But neither side could keep their composure in the final third.

Yevhen Kucherenko's own goal was cancelled out by Luca Stephenson's header just before the break.

United had the ball in the net a further three times, but Zac Sapsford was clearly offside each time.

Leaders Hearts drop points for just the third time this season.

Motherwell bounced back from their League Cup semi-final humbling to save a point against Aberdeen and go three unbeaten in the Premiership.

The visitors' Elijah Just scored from a quick-thinking corner to conjure a quick reply after Jesper Karlsson's second-half rocket put Aberdeen ahead against the run of play.

A third disallowed goal for United! It's Zac Sapsford involved again as he turns in a flicked header from a corner.

He's miles offside, though. The Australian striker has been offside for all three goals United have had chalked off.

Celtic lead struggling Kilmarnock at the break thanks to Johnny Kenny's early goal.

Daizen Maeda should have made it two but inexplicably fluffed his lines from close range.

At the other end, Bruce Anderson hit the bar with Kilmarnock's best chance.

Poor former Dundee midfielder Lyall Cameron... He gets pelters from the home fans as he waits to come on, then has to go and sit down again when Derek Cornelius gets a knock, which means Djeidi Gassama stays on the pitch.

Nasser Djiga is introduced as a defensive replacement instead and Cameron won't get the chance to face his former side.

Kevin Nisbet, Adil Aouchiche and Leighton Clarkson are on for the final few minutes. Can they spark an Aberdeen winner?

This second half has had everything but a goal.

Both sides have run themselves into the ground, put in heroic blocks and laid on a superb spectacle.

Will we get a winner? Both these teams have seen plenty of late goals this season, but in a different way...

Including in the reverse fixture at Tannadice, where Hearts won it at the death.

Luke McCowan smashes a shot high and wide for Celtic.

The midfielder had options left and right.

Nicolas Raskin must think he's scored a second goal as he's left alone in the penalty area again, but this time the midfielder's header is brilliantly clawed away by Dundee goalkeeper Jon McCracken.
