Sean Dyche will be without key midfield personnel once again for the trip to Leicester City on Saturday.
David Jones, Dean Marney and Matthew Taylor all missed last week’s clash against West Bromwich Albion and the game at the King Power Stadium is likely to come too soon for the trio.
Elsewhere in the engine room, Nathaniel Chalobah will also miss out after taking a knock to the windpipe in the U21 Premier League Cup game against Hull City on Tuesday - meaning Dyche may have to shuffle his midfield pack against the Foxes.
Dyche said: “We’re really stretched at the moment, particularly in midfield which is well documented.
“We’ve got injuries to David Jones and Dean Marney and unfortunately Matt Taylor and Nathaniel Chalobah as well.
“Nathaniel went down and took a bad knock to the throat in the week and we’ve been advised that he can’t play due to it being a delicate and important area.
“He’s in no danger but on the night his voicebox and his throat was swelling so we had to get him off and make sure he got to hospital as a precaution.”
The Clarets operated with a 4-1-4-1 system last time out with Steven Reid screening the defence and Scott Arfield and George Boyd operating in the centre of midfield.
And ahead of the weekend, Dyche says he now faces the challenge of finding the right players to fit the system again while maintaining complete belief in the group.
“We now have the challenge of finding the players who can adapt to the task or how we can flex the tactical shape in order to slot players in so they’re comfortable and they’re in the best position.
“It’s finding that balance, with no guarantees of course, because we will arguably have to put people in unfamiliar spots.
“One thing we can guarantee though is that we’ll give everything to win and we’ve seen that so many times.
“There are some stretches to the squad this week, as there was last week, but we’ll get through that.
“We believe in the squad and the team we will send out and we’ll see what happens on the day.”
