Ross County 3-2 Rangers
There will be SEVEN minutes of added time.
George Harmon was injured, and there has been three County goals in the second half, plus seven subs.
Max Sheaf now comes on for County, replacing Simon Murray. That'll get added on, too.
James Tavernier (pen)
The goalkeeper went the right way, but there's too much power on the Tavernier penalty, tucking it into the bottom right corner.
Rangers have a lifeline.
By the way, it's Tavernier's 50th Premiership penalty.
Ross County 3-1 Rangers
Matthew MacDermid goes to the monitor on the advice of Andrew Dallas... and it's given. He points to the spot!
James Tavernier has the ball under his arm.
Ross County 3-1 Rangers
There's a handball check. It hits Brandon Khela, who's only just on.
The slow-mo reveals... it does hit the hand of Khela. It's unfortunate, the ball sails in from a cross, skims off the head of Eli King and hits Khela quite accidentally, but these tend to get given.

Ross County 3-1 Rangers
Another County block denies Abdallah Sima, and as he scurries after the ball, Victor Loturi brings him down and gets booked.
The ball comes in, and Simon Murray puts it behind for another corner. Rangers try again - and it's blocked again. County have been clinical at the top end, and desperate at the back.
They make another two changes. Josh Sims is off to rapturous applause, as is Yan Dhanda. Jordan White, the boyhood Rangers fan, and Brandon Khela come on.
Ross County 3-1 Rangers
Michee Efete is off for James Brown, who makes his first appearance for a month. Efete had been booked, so probably just as well.
County are taking their sweet time every time play stops - and who can blame them? This would be a first win in their 25th meeting against Rangers. What a time to get it.

Todd Cantwell crashes one off the crossbar! What a goal that would have been.
He received the ball about 25 yards out and just curled it towards goal. Ross Laidlaw was nowhere near it.
Ross County 3-1 Rangers
We've also got to consider what this means for Livingston in 12th place.
They'd be 12 points behind County with 15 points available. The trap door edges closer.

You cannot deny that County should be ahead. The warning signs were there for Rangers.
The difference must have been the team talks. Don Cowie - same again, keep the pressure on. They've kept going forward, hit on the break again. Great composure from Sims.
I cannot see Rangers coming back from this.
Josh Sims
It's gone from bad to worse for Rangers!
Eli King skips past James Tavernier in the box and lays it off to Sims. The winger takes a touch, fools Dujon Sterling and tucks it past Jack Butland from close range.
The whole ground is stunned. This was not in the script.

Rangers thought they had their second, but Matthew MacDermid was not to be fooled.
Connor Goldson placed a header back across, and Abdallah Sima went all Maradona to punch the ball into the back of the net.
Whistle goes. No goal.
Ross County 2-1 Rangers
Abdallah Sima bursts forward and strikes a thunderous effort at goal - but as he has done many times this afternoon, Ross Laidlaw keeps it out. The ball comes back to Sima but he lashes wide.
He's been Rangers biggest threat today. Can he have a further impact on this game?

Michee Efete went into the book for fouling Fabio Silva just before the Portuguese attacker was subbed.
Apologies for the delay, it's all happening.
Ross County 2-1 Rangers
Rangers almost level!
The ball drops kindly to Cyriel Dessers in the County box and he fires low, but Jack Baldwin stretches and makes a fine block, sending the ball behind for a corner.
This could be a real siege for County. How long can they keep Rangers out for?
Ross County 2-1 Rangers
Dujon Sterling and Rabbi Matondo are stripped and ready to come on. Fabio Silva is off and he's furiously muttering to himself as he's hooked, tearing the tape off his wrist bands like a stroppy teenager.
Borna Barisic is also hooked. He just shakes Philippe Clement's hand.

We have a massive 40 minutes to go. Rangers have been in second gear, but County have moved through the gears and they are deservedly 2-1 ahead.
George Harmon
Oh my goodness!
Simon Murray is picked out on the left by Yan Dhanda, he bursts forward and curls towards the bottom corner. Jack Butland produces a good save but it's on a silver platter for Harmon and this time he buries it.
This game has been turned on it's head - and the title race with it.
