Roland Idowu and Marcus Fraser both pick up bookings for St Mirren.

This game is becoming quite stretched as the visitors try to find a way back into it.

Superb stuff from Ibrahim Said, skipping through three chasing Celtic defenders. You get the impression even he doesn't know what he's going to do next. It's mesmerising.

Auston Trusty hauls him down, tugging at his shirt. Ye can get it later, son...

Into the book the Celtic defender goes.

Dundee haven't let up now they've got their goal. There's a loose ball in the box that Ryan Astley tries to curl home but he whips it just wide.

They're going for it here.

Ah, Celtic welcome.

Substitute Shin Yamada forces Calum Ward into a save.

Should be doing better.

Dearie me, Celtic.

One ball and Elijah Just is tearing away from the halfway line and forcing Kasper Schmeichel into a save.

The Celtic 'keeper spills but clears on the second attempt.

It's kamikaze defending from Celtic.

They are so exposed.

Three changes at the start of the second half for Celitc.

Luke McCowan, Shin Yamada and Arne Engels are on.

Paulo Bernardo, Kieran Tierney and Daizen Maeda are off.

It's still all United and they are denied for a second time by a post.

From a short corner, midfielder Craig Sibbald sends a curling drive against the near upright.

Then Jerome Prior has to push away an effort from Zac Sapsford at the goalkeeper's near post.

Youssef Chermiti spins out of one tackle and beats another St Mirren defender down the right before slipping a nice pass into Djeidi Gassama's path.

The winger chops inside and has his shot blocked behind for a corner.

Dimitar Mitov makes a great save to push away John Mulligan's effort.

Aberdeen are holding on a bit here.

Motherwell absolutely terrific in that first half. If you don't know better you'd think they were the reigning champions and not Celtic, who have been awful. Out-played and physically bullied. No shot on target, five touches in Motherwell's penalty area. Men against bhoys so far

St Mirren should be level.

Mikael Mandron has a clear sight of goal after John Souttar gives away possession cheaply, but Jack Butland gets down sharply to his left.

Dan Nlundulu then manages to miss the target from a yard out, but it would have been disallowed for offside had he scored.

And again, Dundee miss a sitter!

Once more, it's a corner that they threaten from. The ball drops to the back post but Billy Koumetio cannot guide it in and Killie clear their lines.

Charlie Mulgrew

Motherwell are absolutely schooling Celtic.

They need to get better at their press, it's terrible and being exposed.

Charlie Reilly has gone into the book for a cynical tug as Kilmarnock tried to break away. First card of the night.

They have a shot moments later, as Yan Dhanda has a pop from distance. Tobi Oluwayemi palms away.

Elie Youan unleashes a fierce drive from inside the box, but it drifts wide of the far post.

Hibs have been bright after the break.
