Steven Defour has been ruled out of Burnley's home game against Everton on Saturday with a hamstring injury.
Clarets boss Sean Dyche confirmed the Belgium international midfielder will not be fit for the match at Turf Moor, but said he hoped the 28-year-old will return before too long.
He said: 'Steven has a straightforward injury and we're not expecting a long lay-off.'
The news is a big blow for Burnley as Defour has become an essential player for the newly promoted side since joining for a then club-record £7.
