Wayne Rooney has "more than one fracture" and needs a "miracle" to be fit for the World Cup, according to England coach Sven-Goran Eriksson.
Rooney broke a metatarsal bone against Chelsea
The striker, 20, had a second scan on his metatarsal on Wednesday.
Eriksson said: "I knew yesterday [Tuesday] that he had more than one fracture. Miracles happen in life now and then, but I don't really know."
Manchester United believe Rooney is six weeks away from training but Eriksson may still include him in his squad.
England and Manchester United's medical teams meet on Thursday to discuss Rooney's chances of making the finals.
Rooney broke his foot against Chelsea on Saturday and an initial scan after the match revealed just one fracture.
And reports suggesting that the 20-year-old would definitely miss the World Cup have been played down by United.
A statement said: "Despite stories in the press we believe Wayne is still six weeks away from full training."
Eriksson added: "I will probably name him on Monday. It will be 26 or maybe 27 players.
"I will not rule him out until the doctors tell me there is no chance. No-one wants that to happen, everyone hopes he can take part in the World Cup at some stage."
Eriksson confirmed that Rooney would remain at his club to receive treatment for the duration of his recovery.
"I will be updated on Thursday because our doctor goes to Manchester to see [club doctor] Mike Stone."
