Aberdeen face an anxious wait to see how long top scorer Pape Habib Gueye is out.
The Senegal star, who has six goals, missed the 2-1 win over Dundee with a training ground injury. There is genuine concern that the issue could keep him out for months rather than weeks.
Boss Jimmy Thelin confirmed: “I have to wait. It is better to see the experts and then we can go with an announcement. We will see what happens on Monday.”
Gueye returned from a successful loan at Kristiansund and has become a top player for the 100% Dons. They have won their opening 12 games, in the league and cup, under Thelin and Gueye has more than played his part in the run.
The good news for Aberdeen is that Duk is now fit and back in the squad. He was on the bench for the first time under Thelin at Dens Park.
