Rochdale boss Keith Hill will again be without defender Scott Wiseman when Leyton Orient visit Spotland.
Wiseman serves the second game of a three-match ban following his recent red card in the 2-1 win at Oldham.
Dale won 1-0 at Dagenham last weekend but centre-back Marcus Holness picked up a thigh strain and is now set for a fortnight on the sidelines.
And with left-back Tom Kennedy returning to parent club Leicester after his loan expired, Hill is short of numbers at the back.
However, on-loan Hull winger Will Atkinson is available for selection after a hamstring injury.
Striker Liam Dickinson, who joined Dale on loan from Barnsley last week and came off the bench at Dagenham, will hope to make his home debut.
