Arsenal's Kieran Tierney could make his first league appearance for five weeks, having returned from a knee injury to play against Villarreal on Thursday.
Granit Xhaka pulled out of that game with a muscle complaint and will be assessed, while Cedric has recovered from illness.
David Luiz is a doubt because of the hamstring problem he sustained against Newcastle last weekend.
West Brom loanee Ainsley Maitland-Niles is ineligible to face his parent club.
Robert Snodgrass will miss West Brom's final four games of the season with a back injury.
