Crawley will check on Jordan Tunnicliffe ahead of the visit of Port Vale.
Defender Tunnicliffe went off injured during the second half of last weekend’s 3-2 defeat at Barrow.
Fellow centre-half Tom Dallison has undergone surgery on the ankle injury which could keep him out for the season.
Tyler Frost, Sam Matthews and Reece Grego-Cox remain unavailable.
Tom Pope is closing in on a return to action for Port Vale.
The striker has been sidelined since January after suffering a broken arm and damaging shoulder ligaments.
But Pope played just over an hour in a midweek friendly against Hereford to build up his fitness.
James Gibbons and Dino Visser are out with hamstring problems.
