West Ham are hoping to have Michail Antonio available to face Brentford on Saturday after he picked up a knock on Thursday night.
The 33-year-old scored the winner for the Hammers in the 2-1 victory against AZ Alkmaar in the Europa Conference League semi-final first leg at the London Stadium, with Moyes confessing he was considering substituting the forward before his goal.
But Moyes admits that he has been feeling the effect of a knock sustained in the game, with West Ham set to assess the forward among others for the game on Sunday.
