Adams begins a three-match ban after he was shown a straight red card as the Blues won 1-0 at Bolton in midweek.
Adams' absence leaves Birmingham short of attacking options and boss Garry Monk is keen to get Sam Gallagher back in contention as soon as possible. The on-loan Southampton striker has been struggling with a calf injury and he will be assessed again ahead of the game.
Midfielder Craig Gardner could return to the squad following a hamstring problem as Monk's men look for a fourth straight victory to ease them further clear of the drop zone.
Burton hope in-form winger Lloyd Dyer will be fit to play.
The 35-year-old, who was born in Birmingham and had a loan spell at St Andrew's in 2015, is nursing a knock from the home draw against Middlesbrough on Monday.
Dyer has set up two of Burton's last three goals and scored the other, so Albion boss Nigel Clough will be eager to have him available.
Forward Lucas Akins (hamstring) is nearing a return and he will be assessed along with Darren Bent (illness) and Jacob Davenport.
Luciano Spalletti has played down claims there is a problem between him and Inter bosses as he is in the final year of his contract.
Crotone defender Federico Ceccherini has completed his move to Fiorentina on a permanent deal.
