Sven-Goran Eriksson will sit by his phone on Friday praying for good news on England striker Wayne Rooney.
Rooney had an all-important scan on his broken metatarsal bone on Thursday and early unofficial reports hinted that he could play some part in next month's World Cup.
Manchester United doctor Tony Gill will study the results of the scan today and give his verdict to Eriksson and the England medical team.
England's B-team lost to 10-man Belarus last night and reserve keeper Robert Green looks set to miss the World Cup after suffering a bad groin injury.
After a night like that, Eriksson could do with a boost from Rooney.
The England boss said: 'The scan has been done and the doctor will look at it in the morning at 9.30.
'It is important to wait until he sees the scan. Let's wait and see. It is less than 12 hours. Then we will know the answer for sure.
'It will be huge for the country if he can be ready during the World Cup.'
The England manager had not spoken to Rooney since yesterday's scan at a Manchester hospital.
Rooney, who broke his foot on April 29, has been recuperating under the supervision of club doctor Mike Stone.
Stone was sacked earlier this week, amid rumours of a row with Sir Alex Ferguson, but the England boss trusts United to get Rooney fit for the World Cup finals.
Eriksson said: 'Manchester United took the decision they took. I suppose they are extremely well covered behind Mr Stone. I am not worried about that.'
Keeper Green will also have a scan today but seems certain to miss the World Cup after tearing a groin muscle, five minutes after coming on as a sub against Belarus.
Jermaine Jenas had given England the lead in the first-half but the visitors equalised when Green was lying on the turf injured.
Belarus finished the game with 10 men but still grabbed a winner, nine minutes from time.
Eriksson said: 'I am always disappointed to lose but the result was not important. There were more positives than negatives for me.'
One of the biggest plus-points was the performance of teenage Tottenham winger Aaron Lennon.
Eriksson said: 'He played as he has been playing for the last two and a half months in the Premier League. He was exceptional.
'He showed why he is in the squad. He has quick feet and pace and he will be very useful in a one-v-one.'
The England boss was also pleased with Arsenal teenager Theo Walcott, who made his senior debut in England colours even though he has not played in the Premier League yet.
Eriksson said: 'He is 17 years old and my only concern was that he would be nervous and unable to handle a situation like this - but he showed he can handle it.'
Michael Owen, starting his first game since breaking his foot on New Year's Eve, captained the B team but made way for Walcott after an hour.
Eriksson said of Owen: 'He seems to be fit and didn't feel anything after the game.
