The striker sustained a knock to his ankle against MK Dons and missed the midweek defeat at Charlton. If he is ruled out, the versatile Chris Clark is set to continue in an attacking role.
Meanwhile, Onismor Bhasera, who was stretchered off in the win over the Dons with a knee injury but had an outside chance of making the game, may now not be involved as he is in talks with Blackpool over a loan move with a view to a permanent deal.
Reid is already without Bradley Wright-Phillips after the striker left to join npower League One rivals Charlton this week, with Rory Patterson - fresh from his call-up to the Northern Ireland squad - likely to continue up front.
