Ross Tokely and Andrew Shinnie could return from injury for Inverness.
The pair have been sidelined with calf injuries but both could be in contention for the fourth round tie.
Boss Terry Butcher has no fresh injury worries for the visit of the Pars.
Defender Kevin Rutkiewicz and striker Steven McDougall have returned to training and could be included in the Dunfermline squad for the cup clash.
On Thursday goalkeeper Paul Gallacher was ruled out for the season with his shoulder injury, meaning Chris Bell will continue to deputise as the Pars seek reinforcements.
Austin McCann, Nick Phinn and Steven Bell remain absent.
