LONDON, England -- Manchester United midfield player Paul Scholes will undergo knee surgery on Thursday and is not expected to play again until February.
Scholes should be fully fit in time for the Champions League first knock-out phase in February.
The 32-year-old former England international was injured during training on the eve of last week's 4-2 Champions League victory against Dynamo Kyiv in the Ukraine.
Initial tests proved inconclusive, but a second scan on Monday confirmed that Scholes has suffered ligament damage.
A club spokesperson told ManUtd.com: "We can confirm that Paul Scholes has suffered a knee ligament injury. He will undergo an operation on Thursday and will be out for approximately 12 weeks."
Scholes absence has coincided with the return of Owen Hargreaves from injury while a third England midfielder, Michael Carrick, is poised to resume training after dislocating an elbow in European action against Roma.
United will miss Scholes for the conclusion of their Champions group campaign, but he should be fully recovered for the first knockout round first leg on 19/20 of February.
Scholes will miss at least a dozen Premier League games including Saturday's clash against current leaders Arsenal and December's trip to Liverpool.
West Ham's Welsh striker Craig Bellamy could be out for a month after suffering an abdominal strain during Saturday's goalless Premier League draw at Portsmouth.
Manager Alan Curbishley said: "He's had this injury since pre-season. He's been training and playing, but he's been in discomfort, so we've got to sort the problem out."
Bellamy's absence means Carlton Cole is West Ham's only available striker for Tuesday's Carling Cup fourth-round tie at Coventry -- with a place in the quarterfinals at stake.
Dean Ashton and Bobby Zamora are also injured and Henri Camara is cup-tied. E-mail to a friend
