The early injury to Jamie Lawrence with a gashed knee will rule the midfielder out of the Blackpool game and possibly the visit of Rushden next weekend.
The already stretched squad will also be without Craig Armstrong after he picked up thigh strain at Loftus Road.
Jonny Rowan has suspected ligament damage on his ankle leaving Law with just Mickael Antoine-Curier as his only fully fit striker.
Law will now no doubt have to call on the younger members of the squad such as Chris Bolder and Graham Hockless just to put out a team for the Easter Monday game with the Seasiders.
