Frecklington and Revell both suffered knocks in Tuesday's 2-1 Capital One Cup victory over Sheffield Wednesday and are rated as 50/50.
Boss Steve Evans has ruled out striker Daniel Nardiello as he continues to battle a hamstring injury suffered in pre-season.
Danny Hylton, Michael Tidser, David Noble and David Worrall will all be hoping for the nod if Frecklington and Revell do not make it as the Millers look to continue their unbeaten start to the season.
