It travels 30-40 yards, high up in the air to the back post. Celtic just can't defend crosses, can't defend their box.

Terrific save wide by Dundee goalkeeper Jon McCracken after a neat one-two between Mikey Moore and Bojan Miovski, with Moore having the shot.

An attacking switch from Derek McInnes, Blair Spittal is on for defender Michael Steinwender.

Another massive Hearts chance is wasted as Claudio Braga fails to poke in at close range.

Kasper Schmeichel just sticks his left hand out and makes a fine stop before smothering away.

Remember, the second half at Ibrox kicked off a good few minutes after the equivalent at Tynecastle so even when there is an outcome in Edinburgh, there is likely still to be a bit of time left to play in Glasgow.

A cheap, cheap yellow for Oisin McEntee, who loses possession in his own half and pulls the shirt of Benjamin Nygren.

Clear booking.

First changes for Dundee as Fin Robertson and Joe Bevan come on for Callum Jones and Cam Congreve.

Rangers also make a substitution, with midfielder Nedim Bajrami making his return from injury in place of Thelo Aasgaard.

Hearts cannot let Celtic break the play up, take time over free-kicks. They need to make the extra man work for them.

Now we'll see what Celtic are all about. They need to grind it out.

For the second time in three days, Celtic are right up against it with 10 men.

At least they got a bit of practice on Thursday, but will it be the same result?

What a finale we're about to witness at Tynecastle.

Approaching the 80th minute...

Young Dane Murray wins a big, big header in the Celtic defence.

Julian Araujo is then into the book for timewasting at a throw.

From what I saw, I don't even know if the ball is going in the 18-yard-box, it looks like it's going wider.

Is that then a goalscoring opportunity?

I don't think it was [a red], Kabore's not in control of the ball.

Trusty wasn't the last man.

There hasn't been much of a flurry from either side since James Tavernier's penalty opener for Rangers.

Dundee have not made the most of set piece opportunities and, aside from a Thelo Aasgaard run, the hosts have not threatened much either.

After a brief trip to the monitor, the referee upgrades Auston Trusty from yellow to red and the Celtic defender is walking.

Denial of a goalscoring opportunity is the offence. Anthony Ralston will now replace goalscorer Yang Hyun-Jun.

Oh, VAR John Beaton has recommended an on-field review...

Tynecastle is absolutely furious, as are the home players as Auston Trusty is shown a yellow for a tug on Pierre Landry Kabore.

Almost everyone with maroon-tinted glasses will think that's the denial of a goalscoring opportunity, but referee Steven McLean says it's just a yellow.

Kieran Tierney walks off gingerly after some treatment and he will be replaced by Dane Murray, who had a torrid time for Celtic on his last appearance at Tynecastle.

Double Hearts switch as Oisin McEntee and Sabah Kerjota replace Jamie McCart and Tomas Magnusson.
