Havard Nordtveit is West Ham's latest injury absentee ahead of the visit of Middlesbrough.
The versatile midfielder underwent a small medical procedure on Wednesday and will be out for a week.
Left-backs Aaron Cresswell and Arthur Masuaku and forwards Andy Carroll, Andre Ayew and Diafra Sakho remain on the sidelines.
Meanwhile, Aitor Karanka has warned Middlesbrough not to rely upon collecting the points they will need to survive solely at the expense of the Premier League's lesser lights.
Promoted Boro enjoyed a positive start to life back in the top flight when they took five points from their opening three games against Stoke, Sunderland and West Brom and felt they were unfortunate to emerge empty-handed from a home clash with Crystal Palace in their next outing.
