Dundee United skipper Jon Daly requires surgery and is set to be sidelined for up to six weeks.
The striker requires an operation to resolve a niggling hernia problem and is due to go under the knife on Thursday.
Having played through the pain barrier for some time, he feels he can no longer produce his best while struggling with the ailment.
Daly admits he had hoped to battle on until the end of the season, but accepts that he must now take an enforced break.
He told the Daily Record: "I'm going in on Thursday to get the operation.
"I have been playing with it for months but it's got to the stage where it needs to be dealt with.
"It's not the pain that is the problem, I can handle that, but it's now stopping my movement.
"I was training the other day and couldn't move for the ball. So that told me enough was enough.
"Obviously it's not the best timing because we have such a busy schedule.
"I was hoping to get through to the end of the season before having the surgery.
"But it's reached the stage where I just can't go on with it anymore. It's frustrating for myself and for the manager because we don't have too many options.
"I have been told it will be four to six weeks before I'm back but obviously I'll be pushing myself to return quicker."
