STEVEN MacLEAN will go under the knife today, desperately hoping that the surgeon will have good news when he comes round.

The centre-forward pulled out of the weekend derby defeat by Dundee with a knee injury and is worried that he may need major surgery again, after he was ruled out for four months last season with another knee problem. He did, though, bounce back to score in his side's 2-0 cup final win over Dundee United.

With defender Tom Scobbie ruled out for three months with a ruptured ligament, manager Tommy Wright is hoping for good news from MacLean. "The best case scenario is a three or four week absence," said Wright. "The worse case would be more micro-fracture surgery.

"We would be looking at losing him for five or six months in that case. A scan only tells you so much and fingers crossed the problem is down to a floating piece of bone.

"Hopefully we are just looking at a clean-up operation."
