Gelsenkirchen - Greek international Kyriakos Papadopoulos has returned to team training with FC Schalke 04. However, when the 21-year-old will be ready to feature for the Royal Blues in a competitive encounter remains unclear.

The centre-back has been sidelined since November 2012 after suffering several setbacks as a result of tearing ligaments in his left knee, which has stalled any comeback attempts that have been made in recent months.

Elsewhere, is taking small steps towards a recovery. The Dutch striker, who suffered a partial tear of the cruciate ligament in his right knee on August 17, 2013 away from home against VfL Wolfsburg, is still undergoing an individual training routine. Schalke are hoping their star striker could return to action following the current international break, but it remains to be seen how feasible that will be.

Due to a niggling issue in his left knee, is also set for a spell on the sidelines. “The knee is still swollen and an examination of the extent of the injury will follow. The most important thing is that he’s back on the pitch next week,” explained head coach Jens Keller, whose side will take on cellar-dwellers Eintracht Braunschweig following the international break on 19 October, 2013. Three days later the Royal Blues travel to London to face FC Chelsea in the UEFA Champions League, before their clash with arch rivals Borussia Dortmund in the Revierderby on 26 October, 2013.
