Fifa president Sepp Blatter says his organisation is considering paying Newcastle compensation for the serious knee injury suffered by Michael Owen.
Owen is not expected to play again this year
Owen ruptured his cruciate ligament on England duty and is expected to be out for the rest of the year.
The Football Association will also pay compensation to Newcastle.
Blatter said Fifa has put a fund of £6m aside to cover "cases of this kind", but that a final decision would not be made until the end of the tournament.
"The English FA will now have to look at this matter because they made Owen available to play and this will then be put to Fifa," said Blatter.
"This case will be decided at the end of the tournament but this fund does exist for this kind of serious injury."
Magpies chief Freddy Shepherd said he was furious with reports that the FA had taken out additional cover in case Wayne Rooney got injured.
"From what I hear - and the source is good - a separate deal was done for Rooney," he told the Daily Express.
We have one insurance policy in place which covers all England players
"If it's true the FA took out extra cover for Rooney then that is wrong."
But the FA has insisted that it treats all players on international duty the same.
"We have assured Freddy Shepherd that we have one insurance policy in place which covers all England players," said an FA spokesman.
"No additional policies have been taken out, or premiums paid, to cover any individual players.
"This policy compensates clubs for both permanent and temporary injuries sustained by players whilst on international duty with England at a considerable cost to the FA.
"It is important to point out that the FA is one of the very few national associations that has such a policy in place to compensate clubs."
Owen has barely played for Newcastle this year after suffering a broken foot on New Year's Eve, and now faces another long lay-off after the injury in the 2-2 draw with Sweden.
