Schalke's Draxler needs surgery, out for rest of 2014

The 21-year-old World Cup winner, who was already ruled out for the rest of the year after picking up the injury during Friday's 1-0 league win over Augsburg, had further medical checks on Monday which revealed the extent of the problem.

"The midfielder suffered a partial tear of a tendon. In the afternoon he left for Stuttgart to undergo surgery," Schalke said in a statement.

Schalke, who are already missing several players through injury, are in eighth place in the Bundesliga.

They take on Sporting in Portugal in the Champions League on Wednesday.
