England striker Michael Owen has been ruled out of action for around five months after a scan on his injured right knee confirmed serious cruciate ligament damage.
The Newcastle United ace had to be stretchered off early on in the 2-2 draw with Sweden in Cologne, with England coach Sven-Goran Eriksson fearing that the injury was a serious one.
Those fears have proved to be correct, after Owen underwent a scan on his injury on Wednesday morning.
Owen told TheFA.com: "Obviously it's a massive blow to suffer the injury and be out of the World Cup. As soon as it happened I knew I was in trouble.
"I'll go back home now and work with the Newcastle medical staff to put a recovery programme in place.
"My main objective is now to get fit as quickly as possible for Newcastle United.
Coach Eriksson added: "Michael has had terrible luck with injuries since Christmas.
"I feel very sorry for him to miss out on the rest of the World Cup, it's a blow to him and a big loss for the team.
"However, I am sure Michael will work very hard to get back as quickly as possible for Newcastle and England. He is a true professional and a very mentally strong person."
Eriksson also has doubts over defenders Rio Ferdinand (groin) and Gary Neville (calf) for the last 16 clash with Ecuador.
