Madrid - Real Madrid striker Ruud Van Nistelrooy will be out of action indefinitely and may need an operation on his troubled right knee, sports daily AS reported Friday on its website.
The Real doctors carried out stringent tests on Van Nistelrooy's right knee on Friday morning, without yet deciding whether he will need a cartilage or ligament operation.
According to AS, they now want to consult with doctor Steadman, the specialist who operated upon Van Nistelrooy's knee in 2000.
