Dundee are claiming for a penalty as Yan Dhanda's effort at the back post is blocked by Keelan Adams.

The Falkirk right-back was turned away from the ball but it's hard to tell whether it struck his arm.

The three points are totally up for grabs.

Oh dear, Callum Slattery.

The midfielder did so well to take a touch when he received Elijah Just's cut-back. That took him away from the defender, and he just needs to hit the target, but he flashes it way over.

And that might just have been the chance for Motherwell.

What a way to mark his return that would have been for Callum Slattery.

Nice observation Billy

Steven Pressley is emptying his bench to try to change the tide of this game.

Simon Murray is off for Emile Acquah, and now Callum Jones, Yan Dhanda, and Tony Yogane are next off the rank.

Cameron Congreve, Joe Westley, and Ethan Hamilton make way.

Falkirk change this up too with Alfredo Agyeman and Brian Graham on for Kyrell Wilson and Ross McIver.

That might just have been the chance for Livingston.

You can imagine the groans from the Livingston supporters around me...

Big chance for Livingston and Tete Yengi.

A cross from the left falls kindly to the big Australian and he takes a good touch, but can't poke it underneath the keeper.

Feels like there's another goal in this - but which way?

Jonah Ayunga swings an effort towards goal but floats it wide. He's got to hit the target there.

Macaulay Tait is off for Livingston, with Man City loanee Mahamadou Susoho coming on. I wonder what reception he'll get from David Martindale...

A wee high five, nothing more. It's been an afternoon to forget for Tait.

Kristijan Trapanovski (eventually) comes on to replace Luca Stephenson

Luca Stephenson goes off, after taking a bit of a battering in the first half.

United playing with 10 at the minute.

I'd expect a United change or two.

St Mirren have bossed the major part of this second half and look by far the likelier side to score at the minute.

Calvin Miller and Dylan Tait both force Jon McCracken into good saves as Falkirk pile on the pressure.

Craig Sibbald is the first Dundee United player to enter the referee's book after a challenge on Killian Phillips, who was frustrated as play was brought to a halt.

Motherwell have the ball in the back of the net, but the flag is up.

Elijah Just looked off as he burst through one-on-one, before rolling it sideway to Apostolos Stamatelopoulos, who rolled it into the net.

The replay makes it look very close... but the offside stands.

Falkirk are flying all of a sudden!

Equaliser then hitting the woodwork and the home fans are in full voice.

Can’t help but think Jon McCracken’s mistake gave the Bairns huge encouragement.

A great ball flashes across the face of goal by Conor McMenamin but no takers for St Mirren to take the lead.
