Gelsenkirchen - FC Schalke 04 captain could miss the Royal Blues' upcoming clash with Eintracht Braunschweig after suffering a suspected muscle tear during Wednesday's 3-1 UEFA Champions League defeat at Real Madrid CF.

The 26-year-old was replaced in the 58th minute at the Bernabeu, having only recently returned to full match fitness following a thigh problem.

Farfan in contention

Schalke head coach Jens Keller is already without left-back Christian Fuchs for Saturday's encounter, but is expected to have winger Jefferson Farfan back at his disposal after a three-week lay-off with a knee injury.
