Schalke 04's Dutch forward Klaas-Jan Huntelaar suffered concussion during Friday's 2-0 Bundesliga loss to Bayern Munich, his club confirmed on Saturday.

Huntelaar, 33, left the pitch after 67 minutes after suffering a head knock during an aerial challenge.

But Schalke's medical team believe he should be fit to play for the Gelsenkirchen side in Thursday's Europa League opener at Nice.
