Aberdeen defender Ash Taylor faces a late fitness test to determine whether he'll be ready to face Celtic on Sunday afternoon.
The Dons welcome Neil Lennon's side to Pittodrie at noon as they look to become the first team to take points off the Premiership leaders since the winter break.
Derek McInnes' squad has struggled with injuries this season but midfielder Craig Bryson is ready to return.
Taylor may also be able to feature after a calf injury but will be assessed in training on Saturday to determine whether he can return.
Greg Leigh (shin) and Scott Wright (knee) remain on the sidelines.
Aberdeen have lost their last nine home matches against Celtic in all competitions, and haven't scored against the Hoops at Pittodrie in their last three.
Provisional Aberdeen squad:
Lewis
Logan
Hernandez
Considine
McKenna
Taylor
Devlin
Gallagher
Hedges
Anderson
Ferguson
D Campbell
