Newcastle United's Welsh international striker Craig Bellamy has flown to the United States to have surgery on his left knee in the next 24 hours, the premier league club said today.
Bellamy has been suffering with tendonitis in his left knee for several weeks and previously had the same problem in his right knee.
A statement from Newcastle United said: "The problem flared up again during his last international duty and it was felt that following further consultation surgery would be the best option for Craig.
Bellamy will be treated by Colorado surgeon Richard Steadman, who has already helped several players with knee problems.
Newcastle had hoped that by resting the knee and following a special exercise programme Bellamy's injury would settle down. He played the full 90 minutes in Wales' final Euro 2004 group qualifier against Serbia and Montenegro nine days ago.
But United manager Bobby Robson has not pinned any blame on Wales manager Mark Hughes, after the striker was forced to miss his club's 1-0 win at northeast rivals Middlesbrough.
"I have spoken to Mark Hughes at length on Friday and I have no problems with the Welsh FA whatsoever because they have a competent medical staff," said Robson.
Wales face a two-legged Euro 2004 playoff against Russia next month with the first away leg on November 15th.
