West Ham will assess a number of unnamed players who sustained minor injuries against AZ Alkmaar on Thursday.
Forward Gianluca Scamacca has been ruled out of their remaining fixtures following knee surgery.
Leeds captain Liam Cooper has returned to training after injury.
They are definitely without the suspended Junior Firpo and injured quartet of Tyler Adams, Stuart Dallas, Marc Roca and Luis Sinisterra.
CHRIS SUTTON'S PREDICTION
West Ham are essentially safe now. So, Hammers boss David Moyes has been quite entitled to focus on his side's Europa Conference League semi-final with his team selections in the past week or so, even if it has meant they have lost four of their past five Premier League games.
