Celtic vs Aberdeen - LIVE updates
It's the second Scottish Cup semi-final of the weekend as Celtic and Aberdeen face off for a place in the final.
The winner will take on Robbie Neilson's Hearts after they defeated arch-rivals Hibs 2-1 in a pulsating end to the game on Saturday night.
It's only been seven days since these two last met but they get primed for battle again with the Hoops looking to do an unprecedented quadruple treble and the Dons aiming for a first Scottish Cup win since 1990.
Last Sunday, they had one of the games of the season in an incredible match that had more twists and turns than a corkscrew.
Neil Lennon starts with Nir Bitton in the centre of defence after Kris Ajer's injury ruled him out but his side is boosted by the return of talisman Odsonne Edouard up front.
Derek McInnes brings back Sam Cosgrove and Scott Wright in an attacking line-up while Marley Watkins returns from his injury to add pace on the flanks. Jonny Hayes has missed out on the squad completely.
