Martin Odegaard has suffered a medial collateral ligament injury, which will rule him out of several upcoming games for Arsenal.
Odegaard's injury occurred during a clash with West Ham winger Crysencio Summerville on October 4, forcing him off the field after attempting to play on twice.
This is not Odegaard's first injury, as he previously suffered a shoulder injury against Nottingham Forest and missed two months of last season with an ankle sprain.
No official statement from Arsenal on the exact duration of Odegaard's absence.
Arsenal and Norway will have to wait for Odegaard's recovery, as he faces another extended period out of action.
