Scannell pulled his hamstring in the dying stages of the 2-1 win over Charlton, so Solomon Taiwo should come back into midfield.
Defender Damien McCrory remains on the sidelines after he twisted his ankle at Bristol Rovers a fortnight ago, with Oluwafemi Ilesanmi continuing at left-back.
Striker John Akinde is back in training after a long-term groin problem, but is not yet ready to make his Daggers debut.
Defender Will Antwi has also returned to full training after a groin problem, but will not dislodge Scott Doe and Mark Arber in the centre of defence.
