The 26-year-old joined the League Two leaders last week following his release by Championship side Sheffield Wednesday and is likely to make his debut on Thursday.
Fellow new signings Lee Hughes and Darren Purse are both expected to keep their places in the side after impressing during Vale's win over promotion-rivals Gillingham last time out.
Adams will give late fitness tests to injured duo John McCombe (medial ligament damage) and Louis Dodds (knock).
Both players missed the 2-1 victory over Gillingham, but with Saturday's match against Bradford falling victim to the weather, the pair have had extra time to recover and could return to action.
