Ross County will be without Ivan Sproule and Stuart Kettlewell for Saturday's Scottish Premier League encounter with Kilmarnock.
Sproule has not recovered from the injury that forced him off early in the second-half of last weekend's defeat to Inverness, while Kettlewell is suspended.
Goalkeeper Mark Brown remains out with a broken hand but captain Richard Brittain returns from suspension.
Kilmarnock are set to be without Cillian Sheridan, who injured a metatarsal in training this week.
Paul Heffernan is also suspended, which could pave the way for Kris Boyd to make his first start since returning to Rugby Park.
The striker is back at his former club following a spell in the United States but boss Kenny Shiels has remained coy over his chances of being involved.
"It might be a bit early - maybe the St Mirren game (on Wednesday)," he said. "He's been working hard over the break and he has used those three weeks to keep himself fit and sharp.
"Everybody else is raring to go. It will be a hard match. They have done really well. Derek (Adams) deserves so much credit and hopefully he gets it."
