Rovers will give Jason Lowe as long as possible to prove his fitness ahead of Friday's match against Bolton Wanderers.
Last Saturday against Charlton saw the Rovers midfielder limp off during the second half with discomfort in his foot on his return to action from the same injury that kept him out since the end of August.
But whilst Lowe is a doubt, the boss Gary Bowyer does welcome back Tom Cairney and Chris Brown to the squad after ankle and knee injuries.
"The only player we are really looking at is Jason Lowe," said the manager.
"Tom Cairney has trained this week, as has Chris Brown, we've been really pleased with them.
"So the only one at the moment is Jason Lowe and we'll give him as long as we possibly can.
"If he doesn't make it then it will be a blow, he's an unsung hero, he doesn't get the credit he deserves."
Whilst Lowe is touch and go for the Boxing Day clash, one player who definitely misses the match at the Macron is Alex Baptiste.
The defender is ineligible to play against the Trotters due to them being his parent club.
"It is a blow to be without Baps as I thought it was his best game on Saturday against Charlton," added Bowyer. "Going forward he was immense for us.
"But it was part of the deal and what it now does is it creates an opportunity for somebody else to go and have a right good go and stake a place in the team."
