Manager Stephen Robinson has confirmed that Greg Kiltie is expected to miss three months of action.
The 27-year-old midfielder underwent an operation for an ankle injury last week.
Speaking after our 2-2 draw with Fleetwood Town on Saturday, the manager said: "Greg has had an operation on his ankle unfortunately and joins Conor McMenamin in the region of three months.
"They are both big blows for us and are an integral part of the system that we played last year. It's up to people now to step up and grab the opportunity."
Everyone at the club wishes Greg a full and speedy recovery.
