The 29-year-old joined the Eagles from the Hammers in the summer for around £9.5 million, and he has gone on to become a really important player for Roy Hodgson's side, making 25 appearances in all competitions for the south London outfit.
Crystal Palace currently sit in 14th spot in the Premier League table, six points and two places behind West Ham, so Saturday's game will be a vitally important one for both sides.
According to a report from Football.London, the Eagles might have to do without Kouyate, however, after the midfielder picked up an ankle injury against Southampton just over a week ago.
Having the Senegal international unavailable will be a big blow for Palace, and with West Ham buzzing after their fine performance against Liverpool on Monday night, Hodgson's men could very well have their work cut-out at Selhurst Park on Saturday afternoon.
