Swindon midfielder Jordan Lyden could return from a thigh problem in time to face Cambridge.
Lyden missed the 2-2 draw at Forest Green because of the injury sustained during training but might recover for the Boxing Day clash.
Defender Tom Broadbent also sat out the Forest Green match because of a calf issue and is a doubt.
“We’ll find out in the next two weeks how good our squad is. And we’ll find out about our strength in depth,” boss Richie Wellens said.
Cambridge full-back Kyle Knoyle will miss the entire Christmas period because of the dislocated shoulder suffered against Leyton Orient.
The joint was put back into place after the match but it is the second time he has sustained the injury this season.
George Taft has overcome a calf problem and is available even though he was not selected for the 3-2 defeat against Orient.
“George is coming back from an injury and it becomes a case of who do you leave out for him?” boss Colin Calderwood said.
