Manchester United received a massive blow after Wayne Rooney fractured his left foot in the goalless home draw with Reading in the season's opener on Sunday. The injury was confirmed after the international striker has undergone tests after he was pulled out of the game, reported the club website. "The England striker was substituted at halftime after being caught by Michael Duberry as the Royals defender tried to block a shot," United said. "Although Rooney did briefly play on after receiving treatment, Sir Alex Ferguson opted not to risk any further injury by fielding him in the second half, and a post-match hospital scan has validated that decision. "The result of Rooney's scan has worsened a frustrating opening day of the season, and as yet there is no timescale of his recovery." Rooney, who broke a foot bone during Euro 2004 and just before the 2006 World Cup, is expected to be out for up three months. England will also miss the 21-year-old Rooney during their Euro 2008 qualifiers.
