Pablo Zabaleta could return from illness to face Brighton on Wednesday but Manuel Pellegrini expects West Ham's injury problems to be slow to ease.
Marko Arnautovic returned in yesterday's defeat to Burnley, but Pellegrini warned that fellow forward Javier Hernandez is at least another week away from fitness.
Winston Reid (knee) remains out until late January but as yet there is no timescale on returns for Jack Wilshere, Ryan Fredericks (both ankle), Fabio Balbuena, Manuel Lanzini, Carlos Sanchez (all knee) and Andriy Yarmolenko (Achilles).
Provisional squad: Fabianski, Zabaleta, Diop, Ogbonna, Masuaku, Rice, Noble, Snodgrass, Anderson, Antonio, Carroll, Adrian, Cresswell, Obiang, Diangana, Coventry, Silva, Powell, Arnautovic.
