Midfielder included in weekend squad.
David has been out of action since the 2-2 draw with Gillingham, where he took a blow to the foot in the second half of that match.
The U's have won two and lost two in David's absence, but the former Norwich man will be hoping to make a contribution when the U's take on the Iron this weekend.
The management team will also pay close attention to Sam Walker's progress, as he looks to come back from the knee injury that ruled him out of the midweek defeat to Chesterfield.
