Serdar is understood to have torn the outer ligament in his left knee.
The German international suffered the injury in the second half of Schalke's 0-3 loss to Augsburg on Sunday.
Having scored seven goals in 20 Bundesliga games this season, Serdar has been a key performer for Schalke, who sit eighth in the table.
