Aberdeen striker James Wilson has become the latest addition to Derek McInnes' casualty list.
The former Manchester United striker is picked up a knee injury and will now join Craig Bryson, Greg Leigh, Scott Wright and Zak Vyner on the sidelines for the Aberdeen clash with Motherwell.
However, Lewis Ferguson will be available again after serving a one-match ban against Dumbarton in the Scottish Cup on Saturday.
Motherwell winger Jermaine Hylton is a doubt after going off early against Dundee because of illness.
Barry Maguire and Jamie Semple are also doubts after picking up knocks.
Charles Dunne and David Turnbull both remain out for the Steelmen.
