The 26-year-old fractured the fifth metatarsal in his right foot during the Magpies' 2-0 defeat at Tottenham.

Owen is poised to be sidelined for two to three months and he said: "It is very disappointing.

"But I have no doubts I will be fit for the World Cup - from what the experts are telling me."

England boss Sven-Goran Eriksson has said that he will be monitoring Owen's fitness battle.

The Swede told the Football Association website: "It's very bad luck for him and for Newcastle United.

"Michael is a fantastic striker and a very important player for his club and for England.

"I hope that he returns to fitness as soon as possible and I will follow his progress very closely."

However, Owen conceded that it would be unlikely he would be able to rush back into action after such an injury.

He added: "There is no quick return - I think it is about three months - but loads of people have had it, like David Beckham, Wayne Rooney and Stevie Gerrard, and I have spoken to some of them.

"It is disappointing but everyone gets their fair share. If there is any consolation it is that I have got plenty of time before the World Cup."
