Craig Halkett comes on having not played since Christmas Eve last year with a knee injury.

A big moment for the Hearts centre-back.

Point. Blank. Range.

Top stuff from David Marshall to keep out Bruce Anderson, who surely thought his side-footed finish would end up in the back of the net.

The Hibs goalkeeper makes himself big and the ball bounces off his chest.

Another chance for St Johnstone as a throw-in is nodded into the box and Diallang Jaiyesimi hooks the ball over this shoulder, but it's just over the bar.

Here comes Oli Shaw for Motherwell. He replaces Jon Obika. Will he find the equaliser for Motherwell? Our survey says...

Jamie McGrath bends one past the post for Aberdeen, who have been much better in the second half.

Hearts have completely fallen out of the game. At least for now...

So close to a Dundee penalty.

Substitute Dujon Sterling is reckless with his challenge on Cammy Kerr on the edge of the penalty box.

However, a VAR check rules it is just outside and Luke McCowan fires just wide from the free-kick.

Rangers race up the other end and Abdallah Sima is through on goal only to fire low past the post.

You could almost feel the air and energy being sucked out of Fir Park with that Bevis Mugabi own goal gifting Saints the lead.

'Well, remember, looking to avoid a 13th game without a win but there hasn't really been much response since going behind, with manager Stuart Kettlewell reluctant, so far, to go to a very young-looking bench. He needs something, and quickly

I tell you what, the challenges are flying in all over the pitch at Pittodrie.

The yellow card count has increased in the past few minutes.

Don't be surprised if a red is brandished at some point if this carries on.

There is no doubt the Hibernian disallowed goal thanks to VAR has given the home side a belief they can take something out of this match.

The introduction of Bruce Anderson to partner Kurtis Guthrie up front has also given the home fans a boost with just under 30 minutes left to play.

Dundee are not out of this yet and midfielder Lyall Cameron fires a low drive straight at goalkeeper Jack Butland.

First real save of the afternoon from David Marshall, and it has to be a good one.

Sean Kelly fizzes one goalward from the edge of the box, forcing the Hibs keeper down to his left.

Dylan Vente chases the ball on the follow-up but there's a good block in there to keep the visitors out.

Beni Baningime could be in trouble here.

He clatters in to a challenge with straight legs, and doesn't get the ball.

The referee consults with his other officials and opts to just show the yellow card.

Bojan Miovski and Frankie Kent also get booked for their part in the stramash afterwards.

To put a slight dampener on a very positive St Mirren performance so far, there's a second injury of the afternoon for Stephen Robinson's men as Richard Taylor limps off the park.

Charles Dunne comes on in his place.

Rangers have looked a bit shaky at the back as the 10 men look to protect their lead.

Home substitute Ross McCausland makes an impact, but the winger's low drive from a tight angle is easy for goalkeeper Trevor Carson.

Daniel Phillips collects the ball on the edge of the box and drills his shot just wide of Liam Kelly's right-hand post.

St Johnstone are keeping up the pressure and they look far more likely to score a second than Motherwell getting an equaliser.

Big chance for Aberdeen.

Ester Sokler is played in behind and fires into the side netting.

The angle was fairly tight but he's got to hit the target.

Rangers manager Philippe Clement had made changes at the break, bringing on Ross McCausland for fellow winger Rabbi Matondo and defender Dujon Sterling for midfielder Todd Cantwell.

It suggests the Belgian is looking to tighten up at the back as he looks to protect that lead with 10 players.

Now Dundee's Tony Docherty responds by bringing on attacking midfielder Scott Tiffoney and striker Charlie Reilly for Aaron Donnelly and Zak Rudden.

Despite being a man down, Rangers are looking comfortable so far in the second half. They're keeping the ball well with some lovely passages of play. Dundee at the moment aren't seeing much of the ball at all.
