Jones: Could be out for two months

Jones suffered the injury in training earlier this week and was sent for a scan which has confirmed he requires an extensive period of rehabilitation.

A statement issued by the club read: "Phil Jones has had surgery on a knee meniscus tear sustained in training that will require six to eight weeks' rehabilitation."

It is desperate news for the 20-year-old, who is yet to make an appearance this season.

After an extensive break following Euro 2012, Jones suffered a back injury that prevented him playing any part in pre-season.

He missed United's opening three Premier League games and the start of England's World Cup qualifying campaign, but Jones' return to training was supposed to be the prelude to his comeback.
