Manchester United midfielder Owen Hargreaves will be out of action for five weeks after injuring his hamstring in his comeback match on Saturday.
Hargreaves limped off five minutes after starting for the first time since September 2008 and United manager, Sir Alex Ferguson says the England international could return by mid-December.
Before Saturday’s Premier League win over Wolverhampton Wanderers, Hargreaves had made just one substitute appearance in two years because of tendinitis in his knees.
Ferguson said: “We were at the stage where we knew Owen’s knee was okay.
“His training performances for eight or nine days previously had been terrific.
“He had done really well, which is why we took the chance.
“But maybe the tension in the build-up for the lad was too much and he suffered because of it.”
