Brighton are on a decent run of form and are unbeaten in their last six league matches and have kept five clean sheets in the process.
It's all the more impressive as Graham Potter' s team have had a number of injuries to contend with, especially in the wing back roles.
Victory against Palace this Monday would see Albion leap frog Roy Hodgson's team, who have lost their previous two matches to Leeds and Burnley
Scroll down and click through to see which Albion players are ruled out and which players still have a fighting chance of making the starting XI.
1. Adam Webster
“Adam (Webster) is looking unlikely for the game we are still assessing the damage to his ligaments. So it looks quite likely he will miss the game," said Potter when asked Webster will be fit for Palace. Webster also missed last week's 0-0 draw against Villa having rolled his ankle at Burnley. West Brom on Feb 27 looks more realistic
2. Tariq Lamptey
Was expected to return from his hamstring injury to face Palace but the flying wing back was ruled out. “No he (Lamptey) wont be available on Monday that will be too soon for him," said Potter. "But he is making good progress though, we are hoping that he will back with the group and the weekend and be back in training next week."
3. Alireza Jahanbakhsh
The Iran international is available having recovered from a hamstring problem sustained at Newport in the FA Cup. "Ali, he just needed a bit more time coming back from his injury, but he will be available for the squad on Monday night.”
4. Davy Propper
The Dutch international has had a terrible time this season with injuries and illness. He was on the bench for the Villa match having recovered from his latest groin problem and Potter is optimistic he will be available for Palace. Unlikely to start but he could see some action in the later stages
