Sir Alex Ferguson has revealed Wayne Rooney suffered a groin injury on England duty but is hopeful the striker will be fit for the Manchester derby next Monday.
Rooney was left out of the Manchester United squad to face Chelsea in the FA Cup quarter-final replay at Stamford Bridge after picking up the injury against Montenegro.
Ferguson told ITV Sport: "He got a groin injury playing for England and wasn't 100% yesterday and there's no point risking players with groin injuries because it could exacerbate itself and he could be out for weeks. So hopefully he'll be ready for next Monday's game."
