Crystal Palace manager Roy Hodgson says he expects Wilfried Zaha to be out for around a month with a knee problem.
Zaha was injured in Sunday's 1-1 draw with Newcastle, although he managed to stay on the pitch for the whole of the game.
Initial fears the former Manchester United winger would be out for the remainder of the season have proved unfounded.
But he misses the game against Everton and could also be forced to sit out the Sky Live matches away to Tottenham and Manchester United.
"It's amazing Wilf was able to play so much of the game with the injury," Hodgson said ahead of Saturday's game at Goodison Park.
"He's a very quick healer and we'll be working to get him back as soon as possible. He won't play versus Everton though.
"If he recovered in a week or two it would be a fantastic effort, but it's more realistic we'd have to wait a month for him. It's not certain. He'll be pushing the medical staff to come back as soon as possible.
"Quite frankly I can't remember a time when I've had this many players injured at a club.
"These things happen. We certainly haven't been too lucky of late with injury, but the players have kept battling on and will try to get results.
"We won't feel sorry for ourselves or make excuses. I believe in the 11 I put on to the field."
Palace play an Everton side who were beaten 5-1 by Arsenal in their last match but Hodgson says that has no bearing on their meeting.
"When Arsenal play their best football, they take a bit of stopping," he added. "We were recipients of a 4-1 defeat there ourselves.
"Saturday will be a tighter game between two teams closer together."
