Florian Kamberi is also on for Rangers now and the striker has a sniff of a debut goal, but his shot is saved and the offside flag is up regardless.

Just a few minutes to go across the grounds. Is there time for some late drama?

Don’t be fooled by the narrow lead - Livingston are absolutely bossing this contest. Regardless of tactical tinkering by Stephen Robinson, Motherwell just can’t get a foothold. The only saving grace for them is that with just a goal in it they still have a chance of nicking a point. But it would be robbery.

Hearts now with a big opportunity to level - virtually their first opportunity of the second half.

Uche Ikpeazu barrels down the left and rolls into the path of Donis Avdijaj, who can't quite poke beyond Zander Clark from point-blank range.

What a monumental chance for St Johnstone to kill the game.

Joel Pereira can only parry Chris Kane's shot straight at the feet of the arriving Ali McCann. who lifts over the crossbar on the rebound from a few yards out.

That should have been 4-2 and game over.

Quite a game this in Perth, a great comeback by St Johnstone who have been as good as Hearts have bad in this second half. But for spells they have played some of the best football I have seen from them this season and showed bucket loads of character too.

Ash Taylor meets a free-kick into the box with a thumping header but Rangers keeper Allan McGregor is equal to it with a fine save.

Scott Allan pings in an obscenely accurate long free kick to pick out Darren McGregor in the St Mirren box, but the unmarked central defender can only get his header on target at the front post and Vaclav Hladky dives to push it wide.

Jon Gallagher is looking lively since coming off the Dons bench, this time bringing a save from Allan McGregor after being well picked out by Sam Cosgrove.

What a save by Nathan Baxter.

Chris Burke's corner is met by Dario Del Fabro, but Baxter somehow turns the ball over the bar. That could be a big moment.

Another equisite cross from Cameron MacPherson flies in to the Hibs box and this time it lands on the head of Junior Morias, who glances a header just beyond Ofir Marciano's back post.

Rangers cracking up the pressure and this time Borna Barisic's curling drive is palmed away by the increasingly busy Joe Lewis.
