Promotion from the Championship takes priority for Lampard, meaning that multiple changes could be made to his starting lineup for this high-profile fixture.
Ahead of the midweek clash, Sports Mole looks at how County could line up at the Theatre of Dreams.
Harry Wilson and Mason Mount have also been regulars this term, with the latter scoring five and setting up another in his first 11 games for the club, but one or both of them could miss out on the XI here.
If that is the case then Florian Jozefzoon, who started the wins over Oldham Athletic and Hull City in the last two rounds, may profit in attack.
Evans and Davies will miss out with knee and hamstring injuries respectively, meanwhile, and utility man Anya remains a long-term absentee with a calf problem.
