The Seasiders' squad is suddenly looking thin on the ground, with suspensions and injuries hitting hard.
Jack Robinson must serve a ban for the red card he picked up against Blackburn Rovers on Saturday, while Craig Cathcart has been laid low with a knee complaint.
With Blackpool having kept three clean sheets in their last four outings, maintaining momentum is crucial.
They may, however, have to draft fresh faces into their ranks if they are to keep their Championship promotion push on track.
Rae told the Blackpool Gazette: "We might have to have a look at the loan market as we are becoming a bit fragmented.
"Isiah Osbourne is out injured too, so we are maybe a little bit short.
"We are starting to be a little bit threadbare in a defensive area.
"Hopefully the chairman is in a good mood this week!"
On Cathcart's injury, Rae revealed that the Northern Ireland international may be forced to undergo surgery.
He added: "It looks as if he's nicked his cartilage.
"It looks like he might need some work on that. Whether he needs an operation or if he'll just let it heal, we aren't too sure about yet."
