Joe Efford will miss several months after a scan revealed a tear in his quad that will require immediate surgery.
The American wide man was starting to hit a rich vein of form, but a training ground injury the day before the Rangers game at Fir Park has ruled him out.
The 26-year-old went under the knife on Tuesday (25 October) and he isn’t expected to return to first-team action until into the new year.
“It’s a big blow for Joe as his recent performances have been really impressive,” Steven Hammell said.
“We were just starting training and Joe felt something in his thigh after taking a shot. Sadly, it was worse than we feared, and he has now had surgery to correct it.
“We will support him as much as we can and look forward to getting him back in 2023.”
Meanwhile Louis Moult saw a specialist last week on a troublesome ankle issue. He has had a small procedure this week, with the hope it will allow him to play again within the next week to ten days.
Long-term absentees Nathan McGinley and Jake Carroll are making progress, but neither are expected back for the foreseeable future. Rolando Aarons is currently with his parent club.
