Crystal Palace boss Alan Pardew has revealed that both Jason Puncheon and James McArthur are facing an extended period on the sidelines.
Pardew confirmed the blow during a press conference on Thursday, with Puncheon nursing a hamstring problem and McArthur an ankle injury.
"I have some disappointing news - McArthur and Puncheon are out for a long period. Puncheon and McArthur have both been having fabulous seasons for us, so that's a significant blow," he told reporters.
Yohan Cabaye is expected to return for Saturday's trip to Swansea City, however, as Palace attempt to recover from a poor run of form.
January signing Emmanuel Adebayor could also start in Wales after making his debut off the bench in the 2-1 defeat against Bournemouth on Tuesday night.
