Thistle Scottish Cup run of season 2023-2024 has brought us to Dingwall and a meeting with Ross County. 

There is just one change to Kris Doolan's starting eleven from the eleven that started at Cappielow in the league seven days ago. Scott Robinson's recent impressive showings from the bench earn him a starting slot this afternoon with Blair Alston the player to drop to the bench. 

Remember this tie is played to a finish with extra-time and penalties if required.
