Balde has undergone surgery on his injured knee and he is highly unlikely to ferature again this season according to O'neill:
"It's too early to day yet just how long Bobo will be out for," said O'Neill. "He really needed to get the operation done because it was beginning to cause him a few problems.
"We'll have to wait and see how he gets on but at this moment in time we would have to say that his chances of making the Scottish Cup Final are very slim."
