West Brom captain Jake Livermore serves the final game of his suspension.
Kieran Gibbs is a doubt to face his former club after suffering a muscle injury during the warm-up before Tuesday's defeat by Leeds.
Arsenal are optimistic Bukayo Saka will be fit, while the recently ill David Luiz and Willian could return.
Gabriel remains absent following a positive coronavirus test, while this game is expected to come too soon for Thomas Partey.
