Palace suffered a disappointing defeat at a chilly Selhurst Park as they fell to a late goal in a game of little action against fellow south Londoners Charlton Athletic.
It was a slow start to proceedings in SE25, with neither side having a chance inside the opening 10 minutes.
The first real opportunity landed on the head of Palace's Aaron Wan-Bissaka, who - unmarked - met a cross from eight yards out but couldn't direct it on target at the Holmesdale Road End.
After that there was little action until the 28th minute when Charlton forward Josh Umerah took aim from 25 yards and smashed the bottom of Billy Granger's post, before Karlan Ahearne-Grant was flagged offside on the follow up.
Ten minutes later and Palace had their best chance of the half, Andre Coker getting a shot off after a move which saw Randell Williams latch on to a high ball over the top and fire in a first time cross only to see Coker's effort parried behind by Mitov for a corner.
The second period continued in much the same vein, with neither side creating any real chances to speak of. However, late on, Charlton broke down the right through Umerah, he found Mikhail Kennedy at the back post and the number 10 made no mistake from eight yards, slotting it under Granger with a first-time shot to give the visitors the lead.
Unfortunately there was no way back for the Eagles and it finished 1-0 to the Addicks.
