Joe Hodge goes in strongly on Dujon Sterling and the Rangers defender appears hurt.

Physios on again and this may be another injury blow for the hosts in this first half.

I have liked Dan Neil today, but that was the worst thing he has done.

It was a poor cross, but it was a silly challenge.

Really, really poor penalty gives Motherwell a real lift now.

United appear to have woken up and have enjoyed a bit of possession.

A deep cross is delivered with Zac Sapsford moving in, but the Australian striker is about an inch away from making contact and the ball bounces out.

Kim Min-su steps up hoping to score his first Rangers goal in the absence of captain Lawrence Shankland, but the winger flashes his shot wide.

Big let off for Motherwell.

Dan Neil crosses for Djeidi Gassama and the winger is seemingly barged by Tom Sparrow.

Rangers have a spot-kick.

With a third goal this season, Ryan Naderi has now matched his Rangers scoring tally for last season, having joined in January.

Decent chance for Lewis Smith on the edge of the box, as he's picked out by Mitchy Ntelo, but the Aberdeen winger leans back and skies it over the bar.

Big chance Motherwell.

Regan Charles-Cook and Alex Lowry combine well as Rangers retreat and the former Rangers youth midfielder's low shot is well saved by goalkeeper Ivor Pandur.

It's turned out to be quite an open game in the opening 25 minutes or so.

Tawanda Maswanhise chases a long ball, but James Penrice gets there first to concede the corner.

Emmanuel Longelo delivers for Motherwell, but it is cleared.

The visitors recycle and win another corner and referee Duncan Nicolson has a word with Penrice over something.

Again, Motherwell cannot make the ball stick.

Aberdeen give the ball away in their own half and Erik Ring is played into the box. He cuts it back, with the ball eventually falling to Tom Lowery, but the midfielder's scuffed effort is blocked at close range.

Jamie Brandon's rebound suffers the same fate.

United manager Jim Goodwin looks concerned as United are forced into that early substitution. The returning boss appears to be wearing a patch over his right eye this afternoon.

We're 20 minutes in and we're yet to have a shot on target.

Two sides clearly lacking in confidence at the top end of the pitch.

Before 20 minutes have been played, Mehdi Merghem's game is over for Dundee United.

The winger limps off to be replace with Jesse Randall.

To say it hasn't been United's day thus far would be the understatement of the century.

Better from Kevin Ciubotaru, however, who fizzes in a good shot that brings Scott Bain into action in the Falkirk goal for the first time in the match.

Rangers winger Findlay Curtis is looking lively after having an effort blocked and now crossing for Kim Min-su, whose header is saved by goalkeeper Alex Paulsen.

That'll do Alex Paulsen's confidence a bit of good after that mistake.

The Well goalkeeper confidently claims Dujon Sterling's cross under pressure from a clutch of Rangers players.
