Ravel Morrison s preparations for the new season have been disrupted, with the West Ham midfielder forced to undergo minor groin surgery.
England Under-21 international Morrison, who spent the latter part of last season on loan at QPR, was diagnosed with a problem when West Ham s players reported back for pre-season testing.
A statement on West Ham s website confirmed the player had a minor procedure at a central London hospital on Tuesday afternoon.
It continued: The operation was completed without complications and, following a period of rehabilitation, it is expected the England U21 midfielder will return to training in a few weeks when the first-team squad return from New Zealand.
Morrison joined West Ham from Manchester United in January 2012 and has made 17 league appearances for the club.
As well as enjoying a spell on loan at QPR, he spent the 2012-13 season with Birmingham City.
