Kemar Roofe
Rangers' substitutes combine perfectly.
Former Dons winger Scott Wright sweeps past Matty Kennedy and his low cutback is flicked over the line from close range by fit-again striker Kemar Roofe.

It has been a tumultuous semi-final.
Silence from the Aberdeen fans. Penalties surely the best chance now for the Dons.
Rangers will go for it. Will another former Aberdeen player turn the knife? Scott Wright on for John Lundstram.

Rangers threaten immediately and right-back James Tavernier, who likes a goal against Aberdeen, has a snap shot deflect on to the top of the crossbar.

On this pitch - it's a ploughed field now - Aberdeen are up against it big style and their captain has let them down. Now we know Sakala is okay, I can describe it as a hilariously bad tackle.
He has lost the place entirely. It's extraordinary. It's the reddest of red cards you'll see. He's piled in there with no appreciation of where he was or the significance of the match.

Rangers are preparing a change as former Aberdeen winger Scott Wright is ready to come on...midfielder John Lundstram is off.

You want your captain to lead by example. Stewart just had to use his experience.
He knows it's getting towards the end of the game, he needs to make sure he's doing everything right. Instead, he dives into a challenge.
In the old rules, that would be an ordering off. It's nothing new in football. If you put one in like that, it's going to be a red card.

Former Rangers winger on BBC Sportsound
He's super aggressive and I'm not sure why he's needing to do that. He's not slipped, that's a straight red all day. I was trying to give him the benefit of the doubt, but that's a red every season of your life.
Sakala is a lucky boy that he's not seriously injured. What's he thinking? I can't fathom it.

Ouch!
Anthony Stewart recklessly slides into a challenge on Fashion Sakala, sending the Rangers winger high into the air.
The Aberdeen captain can have no complaints.
Rangers 1-1 Aberdeen
So close to what could have been a winner as we enter eight minutes of stoppage time.
Connor Barron is in behind the Rangers defence, but his shot on the turn is not only wide of the far post but goes for a throw in rather than a bye-kick.
Rangers 1-1 Aberdeen
Some neat passing on the edge of the Aberdeen penalty box and John Lundstram sends a low drive straight at goalkeeper Kelle Roos.

Having been fouled moments earlier by Borna Barisic, winger Matty Kennedy is also booked for a trip on the Rangers defender.
Rangers 1-1 Aberdeen
A loose John Lundstram pass and Matty Kennedy looks to counter for Aberdeen only to be hauled down unceremoniously by Borna Barisic and the Croatia left-back is rightfully booked.
