Hargreaves suffered a dislocated shoulder in training on Friday ruling him out for possibly another 4 weeks.
His United career has been blighted by injuries, and has been sidelined since September 2008 with knee surgery [twice] and hamstring injuries.
While he was set for a return, Friday’s incident could spell the end of the £17 signing’s spell with United, if they decide not to renew his contract this summer.
