Huge chance for Dons right-back Chris Cadden as the ball squirts to him in the box, but George Stanger flies across to block the effort.

Brilliant defending.

And there's another one.

James Penrice centres, a Motherwell foot diverts it into the path of Kevin Kelsy and the Rangers striker hits it off the crossbar and out as he wastes a chance to score a quickfire debut goal.

If Rangers do not win this game, they only have themselves to blame as the chances have been there. The finishing has not.

Defensively, they have been tighter, certainly than they were in Falkirk, but Motherwell have still seen plenty of the ball in attacking areas and may yet get that one big chance.

Over the course of this game it is Aberdeen goalkeeper Marius Muller who has been the busier, having to make several key saves.

What a miss from Daisuke Yokota after an astonishing mistake in the Motherwell defence.

The Rangers substitute is just presented with the ball by Jake Girdwood-Reich, takes a touch and fires high and wide.

Keep it low and hit the target and that's a goal.

Brilliant run from Erik Ring down the left, skipping inside Lewis Mayo to try and get into the box, but he's brought down at the vital moment.

Yellow card for the Aberdeen defender. Free-kick chance for Kilmarnock...

And it's brilliantly saved by goalkeeper Marius Muller, denying Aaron Tshibola.

And Kevin Kelsy comes on for his Rangers debut in place of Kim Min-su, while Daisuke Yokota takes over from Djeidi Gassama, who has had a good game for the hosts.

So close to a debut goal for Zidane Iqbal!

The midfielder tries his luck from outside the box with a wicked strike, but Falkirk goalkeeper Scott Bain produces a great save.

United are pushing desperately for a leveller.

Another chance goes a begging Rangers. Ryan Naderi heads down for Nico Raskin, a defender gets in the way, but the Belgium midfielder eventually shoots and it is cleared off the line.

Killie appear to have seen off the early Aberdeen pressure in this second half and have spent the last few minutes very much knocking at the Dons' door.

Rangers could perhaps do with some fresh impetus.

Kevin Kelsy and Daisuke Yokota are warming up.

Almost a breakthrough for Kilmarnock!

The ball is whipped to the back post and headed at goal by Greg Kiltie, but goalkeeper Marius Muller is able to get his body in front to block.

To more chants of "USA, USA, USA", the Bairns goalscorer Jacob Murrell departs to be replaced with Ben Parkinson.

Joe Gardner also comes on in place of Ben Krauhaus as Falkirk look to protect their advantage.

Midweek scorer Seb Palmer-Houlden replaces Regan Charles-Cook for Motherwell.
