LONDON -- England striker Wayne Rooney will be out of action for six weeks after fracturing a bone in his right foot, his club Manchester United said on Saturday.
"Wayne Rooney has a fracture of the base of the fourth metatarsal on his right foot. He will be out for six weeks," said a brief statement on United's website.
Rooney suffered the injury in United's Premier League defeat at title-winners Chelsea earlier on Saturday after falling heavily under a challenge from Paulo Ferreira after 78 minutes.
He immediately held his foot, grimacing with pain, and was carried off on a stretcher before leaving Stamford Bridge on crutches.
Rooney is seen as vital to England's chances of success at the World Cup which starts in Germany on June 9. England's first match is against Paraguay in Frankfurt on June 10.
The 20-year-old, who has scored 11 times in 29 international appearances, limped out of Euro 2004 when he suffered a foot injury during England's quarter-final defeat by hosts Portugal.
Rooney cracked the fifth metatarsal, an identical injury suffered at the end of 2005 by England striker Michael Owen.
