Manchester United striker Wayne Rooney is expected to be sidelined for a month with a hamstring problem.
Rooney's manager David Moyes says will not be sold despite speculation about his future, travelled to Thailand for United’s pre-season tour on Wednesday but will now return.
United face Wigan in the Community Shield on 11 August and visit Swansea in the Premier League on 17 August.
Rooney could be doubtful for England’s friendly against Scotland on 14 August.
The forward sustained the injury in training and, after a scan on Thursday, it was decided he would return to England for further assessment and rehabilitation.
“Gutted to have picked up a niggling injury, especially as training was going so well. Heading back to Manchester to have it assessed fully but early indications are nothing to worry about,” said Rooney on hisFacebook page .
Last week, Moyes said Rooney would “remain a Manchester United player” despite former manager Sir Alex Ferguson claiming the striker wanted to depart in May, something the player has never officially said.
Rooney, who played under Moyes at Everton, has scored 197 goals in 402 appearances for United.
And captain Nemanja Vidic believed his team-mate was in his “best shape for five years” before suffering the injury.
Central defender Vidic did not fly to Bangkok on Wednesday because of sciatica but is likely to join the tour in due course.
