England and Manchester United striker Wayne Rooney has had a scan on his broken foot and is waiting to hear the results.
Rooney flew back to Manchester from Germany on Wednesday to have the scan at a private hospital in Whalley Range.
A statement from United read: "United doctor Tony Gill, England doctor Leif Sward and specialists at the hospital in Whalley Range where Rooney had the scan, will examine the results and make a decision.
"If Rooney's rehabilitation has progressed as expected then Eriksson will keep the 20-year-old striker in his squad."
England coach Sven-Goran Eriksson has remained optimistic that Rooney would be fit enough to take at least some part in the tournament ever since the striker suffered the injury playing for United in a Premiership clash at Chelsea almost six weeks ago.
England face Paraguay on Saturday before playing Trinidad & Tobago on June 15 and Sweden five days later.
If Rooney is unable to take part in the World Cup, standby striker Jermain Defoe will take his place.
