Klaas-Jan Huntelaar is an injury concern for Schalke 04, second in the German league, ahead of Sunday's clash with Hanover 96 after the in-form Dutch striker broke his nose in Europa League duty.
The 28-year-old was fitted on Friday with a protective mask, but the Royal Blues are waiting to see if their star striker - who has scored 21 goals in 19 matches this season - will be fit to play.
Huntelaar suffered the injury in the 81st minute of his team's goalless draw with AEK Larnaka from Cyprus on Thursday after colliding with teammate Joel Matip.
Schalke are four points behind German league leaders Bayern Munich, who face Augsburg on Sunday.
With 10 goals in 11 Bundesliga games so far this season, Huntelaar is second only to Bayern's Mario Gomez in the league's scoring charts.
Huntelaar has been included in the Netherlands squad which faces Switzerland in a friendly in Amsterdam on Friday, and Germany in Hamburg four days later.
