Burnley are still unable to put a timescale on Charlie Austin's return from a shoulder injury and plan to run further tests on the striker.
Austin missed the closing two months of last season after dislocating his shoulder and suffered a recurrence of the problem during the recent home defeat by Leeds United.
He has sat out the Clarets' last two matches and, after scans showed no fracture or serious damage, he is poised for a sustained period of examination.
"The scans showed a little bit of damage in the shoulder area," Burnley boss Eddie Howe told the club's official website.
"What we are going to do now is push Charlie back into a series of tests until the point where either he breaks down and needs the operation, or he comes back and is fine.
"We will take him down the path of running, shoulder strengthening work, contact and training and playing.
"At any one of those stages he might break down so we can't put any timescale on his return yet."
