Striker Peter Crouch has been ruled out of the Clarets’ trip to Bournemouth after under-going surgery.
The former England international required an appendix operation which also forced him to miss Burnley’s 2-0 win over Wolverhampton Wanderers last Saturday.
And boss Sean Dyche isn’t yet sure how long the January signing will be sidelined.
“We’ll find out more off the specialist, but they’re reasonably happy so far,” said Dyche.
“On the one hand they say an appendix doesn’t do a lot, but when it flares up you’ve got to be careful with it and we’ll have to wait on a specialist view.”
Dyche reported no other injury worries for Saturday’s trip to the Vitality Stadium, where the Clarets will be looking to build on the win over Wolves.
That result opened up a five-point gap over Cardiff City, who currently occupy the one remaining relegation place to be decided in the Premier League.
Dyche’s side has now taken 21 points since Boxing Day to pull themselves out of the drop-zone.
And the boss is looking to keep the momentum going with six fixtures remaining.
“There is always a slight shift in mentality when you win, but the demand has been good here anyway,” he said.
“The lads have been full of energy this week and we’re ready to go.
“There’s more to be done before the end of the season, but we’ve put ourselves in a decent position.”
The Clarets are inching towards safety at the end of a season which saw the club play in Europe for the first time in half a century after finishing seventh last term.
A second successive season in the Premier League in 2017/18 also helped generate record profits – announced last weekend – with Dyche delighted to see the club keep building.
“To make £36m profit is a positive thing,” he added. “This club wants to be strong for years to come and that helps.
“So, with that and the win over Wolves, it’s been a strong week.”
