Celtic and Aberdeen face off at Hampden Park on Saturday (November 2) vying for a place in the Premier Sports Cup final.
The pair played out an entertaining 2-2 draw when they met on Scottish Premiership duty on October 19, but this time someone has to come out victorious.
The winner will meet either Motherwell or Rangers, who lock horns in the second semi-final on Sunday.
There will no doubt be eyes on the match officials, with experienced referee Kevin Clancy taking charge of this one.
He will be assisted by Frank Connor and Daniel McFarlane. While Andrew Dallas will be on VAR duty alongside John McCrossan.
