Muncy is not in the lineup for Wednesday's game versus the Diamondbacks, Juan Toribio of MLB.com reports.
Muncy sat out Game 1 of Tuesday's doubleheader but started the nightcap and went 1-for-4 with a two-run homer, and he'll return to the bench for Wednesday's contest. Justin Turner will serve as the designated hitter while Hanser Alberto starts at the hot corner.
