Rooney suffers fractured footWayne Rooney suffered a hairline fracture in his left foot in United's goalless draw against Reading.
The England striker was substituted at half-time after being caught by Michael Duberry as the Royals defender tried to block a shot.
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.
Immediately after the match, the United Manager told Sky Sports: “We’re waiting to see how the scan goes. We’ve sent him for a scan and hopefully everything’s ok.
“It was painful, he couldn’t really stand on it. I don’t think it’s the same injury as the last, obviously we hope and pray that that’s the case.
“But it was sore and it started to swell so there was no point in trying anything for the second half.”
The result of Rooney's scan have worsened a frustrating opening day of the season, and as yet there is no timescale of his recovery.
