Hull City's promotion challenge has suffered a blow after Robert Koren was ruled out for around three weeks with a hamstring injury.
The midfielder was hurt during last week's match against Southampton and the Slovenian is unlikely to be available until mid-April.
He has scored 10 goals in 37 Championship appearances for the Tigers this season and Nick Barmby has challenged his squad to cope without Koren.
Barmby told the club's official website: "Obviously losing Robbie is a blow because he has been an influential player for us.
"But this is where your squad kicks in and it's an opportunity for somebody to come in and stake a claim for the position."
The Tigers will hope Koren is available to return by the 17th April encounter with Barnsley, although there are five matches before that date.
