Winger Grabban will be looking to make his debut after arriving on loan from Millwall until the end of the campaign.
The Bees are still without defenders Mark Phillips and Ryan Dickson. Centre-half Phillips has suffered a recurrence of his knee injury and left-back Dickson has a hamstring problem.
Another defender, Alan Bennett, has rejoined Wycombe on loan.
David Hunt could keep his place in midfield after being recalled for the 3-3 draw with Colchester.
