Schalke skipper has knee surgery

BERLIN - Schalke 04 captain Heiko Westermann faces a spell on the sidelines after undergoing knee surgery, the Bundesliga club said on Tuesday.

Schalke, second in the league, will be without their versatile captain for several weeks, they said on their website without setting a date for the Germany international's return.

"Surgery was deemed as necessary because of persistent problems in the defender's knee," the club said.
