Sean Dyche believes Kieran Trippier and Danny Ings could be “on the cusp” of rejoining the squad for the final push.
Striker Ings has missed four games since suffering ankle ligament damage at Birmingham last month, while right back Trippier has been sidelined for three games with a tight hamstring.
Both players are set to miss the weekend trip to Watford, where the Clarets look to extend their recent run of just one defeat in 16 league games.
However, along with midfielder Dean Marney, who sits out the second of his two-game suspension at Vicarage Road, Dyche is hopeful of having key players back in the coming week.
He said: “We are probably stretched to our limit at the moment.
“Dean is suspended for one more game, while things are really positive for Kieran, who is close but probably not quite right for Saturday.
“Danny is back on the grass, which is great news of course. He is moving well, so we are hoping that will be a quicker recovery as he continues on his journey back, but Junior has a tight hamstring, so there are a few challenges and it’s probably as stretched as we’ve been all season."
Dyche added: "Everyone was suggesting it would happen, some outside our camp were almost thirsty for it to happen, but we believe in the group and the mentality of the group, so we will go again.
“It’s up to others to decide how they perceive things, but perception and facts are two completely different things and my job is to look at the facts.
“We have got this situation where we are stretched, but we believe in what we are doing and we think the situation could change very, very quickly because we have a couple of players right on the cusp of coming back in.
“We’ll just keep believing, working and doing all the things we’ve done."
Dyche also revealed that striker Sam Vokes will now go under the surgeon’s knife next week to repair a ruptured anterior cruciate ligament. The Welsh international was set to undergo surgery on Wednesday, but the operation has been delayed to allow swelling around the joint to settle.
