Berbatov scored the opening goal in Manchester United's 3-0 win over Burnley atOld Trafford on Saturday but was substituted before the end and headed straightdown the tunnel for treatment.
Immediately after the game Ferguson claimed his £30.75million record signinghad suffered a recurrence of a knee injury which he has been advised to have anexploratory operation on.
False alarm: Dimitar Berbatov
In fact, the former Tottenham star had only suffered a dead leg and while he isa doubt for tomorrow's Carling Cup semi-final first leg at Manchester City, hehas not completely been ruled out.
'I thought Dimitar had got a knock on the knee. It turned out it was a deadleg and we are having a look at that it. I am hoping he will be all right but he is a doubt and we will see what he islike in the morning.'
Missing out: Ryan Giggs
Ferguson also confirmed Ryan Giggs would not be considered, and neither willRio Ferdinand, even though the England star is continuing to edge closer to acomeback after three months out with a back injury.
'Rio is training quite well now,' he said.
'He is a lot closer now but he isnot in contention for tomorrow.'
However, the United boss is considering whether to add a bit of youth to histeam in the form of Darron Gibson and the Da Silva twins Rafael and Fabio.
Having already absolved the younger members of his side from blame for theshock home FA Cup defeat by Leeds, Ferguson would have no qualms about puttingthem into such a high pressure encounter.
But it does seem the United boss intends to select a far stronger team than theone he originally intended when the draw was made last month.
'I have got to think about getting a mix in terms of the programme we have gotand also the fact I have given young players a game in the past,' he said.
'I will have a strongish team but there will be some young players as well.'
