West Ham striker Marko Arnautovic has been ruled out for a month with the hamstring injury he suffered in Tuesday’s 3-1 win over Cardiff.
The Austria international will miss the Christmas period, although he could be available for the FA Cup third round tie against Birmingham in January.
The 29-year-old has scored five goals in 13 league appearances this season.
West Ham will take on Crystal Palace at the London Stadium on Saturday.
