Ukraine international Andriy Yarmolenko will miss West Ham's Premier League game at Liverpool on Saturday.
The forward was given time off last week following Russia's invasion of his homeland and is not ready to return to the field this weekend.
Speaking at his pre-match press conference, manager David Moyes said: 'He has been training but he won't travel to Liverpool with us.
'I don't think he's quite ready and we want to give him every opportunity to do everything he can for his family and for his country.
