Burnley winger Johann Berg Gudmundsson is set to miss their clash against Leicester City.
The Clarets will have to do without the Icelandic star as he was injured on international duty.
Gudmundsson did not complete his country's 1-0 defeat against France last week.
The attacking midfielder has one goal in four Premier League appearances this season.
Speaking at a press conference, Burnley boss Sean Dyche said: "Johann Gudmundsson won't be figuring.
"Unfortunately he got injured on international duty, a reasonably serious hamstring injury, so it certainly won't be days, it will be more like weeks and I don't know how many yet, but it's serious enough to speak in that way."
