The Daggers have not played since November 23 but did play a behind-closed doors friendly with Gillingham last Friday which saw Antwi (groin) and Tomlin (ankle) pick up injuries.
However the duo were not seriously injured and are both in contention for the long trip north.
Goalkeeper Chris Lewington injured his thigh at Plymouth at the end of last month but is now back to full fitness so loan signing Simon Locke, from Reading, is unlikely to feature.
Watford defender Eddie Oshodi could be in the squad for the first time since signing on a month-long loan while Scott Doe (ankle) and Josh Scott (ankle) could feature after returning from long-term injuries.
