On loan defender Danny Wilson has a thigh injury and is a doubt for Hearts when they travel to Dens Park on Saturday.
Michael Ngoo, also on loan at Tynecastle from Liverpool, is struggling as the striker tries to overcome the shoulder problem which forced him off during the 1-0 victory at Kilmarnock last week.
Hearts boss Gary Locke could bring in 16-year-old defender Jordan McGhee to give him some experience now that the team's top flight status is secured.
New Dundee manager John Brown hinted goalkeeper Rab Douglas has probably played his last game for the club ahead of the match with Hearts.
Douglas has not been at the club in recent weeks, and on loan stopper Steve Simonsen will continue between the sticks.
The Dark Blues, who must beat the Jambos to avoid relegation, are also without long-term absentees Stephen O'Donnell (knee) and Jamie McCluskey (Achilles).
Dorrans came close to departing The Hawthorns during the winter transfer window after asking to leave the club.
The Scotland international ended up staying and has won his place back in Steve Clarke's plans and admits he is happy to stay as long as he is playing regularly.
"I did have a chat with the manager (before Christmas). Everybody wants to be playing and I wasn't playing as much as I would have liked," Dorrans said.
"Had the opportunity come along to go and get games somewhere, we'd have looked at it, as the gaffer mentioned.
"But it didn't, I worked away and got myself back in the side and that's where I want to be."
Dorrans is refusing to rush into any decision on his future saying: "I need to wait and see. I will get through the next five games and see what the summer holds. But I'm playing every week so I'm quite happy at the moment.
"I just wanted to play football. It wasn't to move back to Scotland. Nothing has changed.
"My views were that I want to be playing every week and I've still got the same views. If I can do that I'm happy, if not then I'm not happy, just like anybody else."
