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.
5. Danny Welbeck
Working his way back to fitness after a knee injury. Came of the bench at Burnley and also against Aston Villa and so very nearly scored the winner but was thwarted by another fine save from Martinez. Potter admits he's not ready for 90 minutes but he could used from the bench once more against Palace
6. Alireza Jahanbakhsh
Last seen in the FA Cup against Newport where he suffered a hamstring injury on the heavy surface at Rodney Parade. Is expected to be available for Palace but highly unlikely to start and could offer Potter another attacking option from the bench
7. Jason Steele
The Brighton stopper is back in full training after recovering from illness. Robert Sanchez will take the gloves for Palace and Steele will battle with Christian Walton to be the back-up on matchday.
8. Solly March
Suffered a knee injury at Liverpool and underwent surgery last week. Graham Potter said the operation went well and March now starts a 12 week recovery period
