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.
Leyton Orient have been dealt a double injury blow.
Defender Elliot Omozusi and midfielder Adam Chambers face up to a month on the sidelines after suffering hamstring injuries.
Omozusi was injured during last weekend's FA Cup win at Norwich and was replaced at right-back by Andrew Whing, who is now expected to start his first game since rejoining from Brighton.
Chambers, who was on the bench at Carrow Road, pulled up in training on Monday and faces another spell in the treatment room having missed much of the season with calf trouble.
Teenager Harry Kane should be among the substitutes following his recent loan switch from Tottenham along with fellow striker Ryan Jarvis, who was cup-tied last week.
