Andy initially damaged cartliage in his nose during a pre-season friendly only to suffer a more serious injury in midweek practice. He will undergo an operation tomorrow to correct the problem.
Andy said: "It was a collision with new squad-mate Graydon Staniforth that caused the real problem.
"My nose wasn't pretty at the best of times, but now it is completely out of shape.
"It is very frustrating. However, the sooner I get it fixed the quicker I will be able to return to action."
