Wayne Rooney had his broken foot scanned on Thursday will discover whether he has a chance to play in the World Cup finals when he learns the result on Friday.

Specialists will analyse the scan result with Manchester United's assistant team doctor Tony Gill before informing England's team doctor Leif Sward.

FIFA has imposed a deadline of 30 May for England to indicate whether Rooney is likely to be fit to play.

"Each team has to confirm by May 30 that their players are fit," said FIFA medical officer Dr Jiri Dvorak.

"If Rooney is on the list that is confirmation it is anticipated he will have recovered in time to participate."

However, if Rooney broke down with the foot injury between 30 May and 9 June coach Sven-Goran Eriksson would still be able to replace him in his squad.

Depending on Rooney's progress, he could resume light training immediately after the outcome of the scan is known.

Rooney suffered the injury in United's 3-0 defeat by Chelsea on 29 April.

United insist the departure of Dr Mike Stone, the physician who was in charge of Rooney's recovery, is not connected with the England star.

"Dr Stone has left after a difference of opinion on a non-footballing and non-clinical issue," said a statement.

"It had nothing to do with any medical treatment to a United player."

However, the statement did not specify with whom Stone had the difference of opinion which has led to his departure.

Stone, who had been at Old Trafford for 10 years, has liaised Sward and given him updates on the 20-year-old striker's condition over the past few weeks.

United manager Sir Alex Ferguson has been playing down Rooney's hopes of playing in the World Cup while Sward has always remained positive following his consultations with United's medical staff.

Earlier this week Sward claimed Rooney was making "a perfect recovery".

Stone left United on Monday and emailed his former colleagues at Old Trafford to tell them: "I am leaving with immediate effect, it has been a pleasure working with you all."
