As in 2018/19, the on-loan forward cannot face the Blues while not on a permanent contract at Palace, as Premier League rules dictate.
This leaves a gap in Hodgson's selection, which has been filled by centre-back Scott Dann, who returns to the fold after two matches on the sidelines.
Looking at Chelsea, Frank Lampard updated on squad fitness earlier this week - revealing:
- Christian Pulisic is fit enough to make his squad but not to start, hence being named on the bench
- Summer signing Hakim Ziyech is "getting closer but is not quite fit enough to be on the bench"
- Billy Gilmour remains absent for the following four weeks
Hodgson had a very positive update for Palace fans on Friday, revealing that Patrick van Aanholt, Gary Cahill, James Tomkins and Scott Dann are all training - with Jeffrey Schlupp nearing a return.
He did advise, however, that they are not "really ready to go straight back into the team."
