Pulis said that Chamakh, who has been out since the start of last month, might not start but would be likely to play some part against the Premier League's 18th-placed side.
"Most of them are fit, Chamakh has trained all week with us and he looks ready to go," he told Sky Sports News. "Whether we start him or whether he's involved on the bench, we'll have to wait and see.
"He's been outstanding for us. He's been for me the player that gives us a little bit different within the group so we'll see. It's a decision that I'll make most probably closer to the game."
Palace, in 16th, are two points ahead of Cardiff, who occupy the final relegation spot.
