Crystal Palace boss Patrick Vieira would not confirm whether three of his players will be available for the upcoming Africa Cup of Nations.
Jordan Ayew, Cheikhou Kouyate and Wilfried Zaha were all due to travel to take part in this month's tournament.
But Kouyate and Zaha were both absent for the loss against West Ham United, with Ayew limping heavily at the end.
Vieira said the first two were "not available" to play, adding "no comment" when asked about their Afcon chances.
When questioned by BBC Sport about Ayew's possible injury, he said: "I don't know, I haven't spoken to the doctor yet."
