Richard Shaw's Under-23 side fought hard to earn themselves a draw away against Cardiff City, with the first team's Scott Dann featuring for 77 minutes.
Cardiff started the game well, scoring on six minutes after an immediate bout of pressure resulted in a Gary Madine header finding the back of the Eagles' net.
Fighting to bring themselves level in the game at the other end of the pitch, Palace's Levi Lumeka found a curved effort well saved by the home side's experienced 'keeper, Alex Smithies.
But Palace's young side struggled in the first half against a seasoned, threatening Cardiff who won the ball from the Eagles frequently while producing a series of driving offensives down both of Palace's wings.
Their assault almost yielded success, as Palace shot-stopper Joe Tupper found himself at full-stretch to deny City's James Waite.
A resolute defensive performance from Nikola Tavares and Oliver O'Dwyer kept Palace's goal guarded going into half-time, however, and manager Shaw changed his side to a 4-3-3 formation to put pressure on the home side.
The tactical switch appeared to work and Palace were more confident in the game's second half, finding themselves on the front foot.
The hosts made two substitutions in response and the match had levelled out markedly, with each team playing well.
In spite of Palace's new found gusto, it was Cardiff who were celebrating next as Jamie Veale tapped home from close-range to double the Bluebirds' lead.
The Eagles reacted magnificently, with a young team that included 16-year-olds TQ Addy, Brandon Pierrick and Malachi Boateng not letting the home side's advantage get the better of them.
Lumeka opened Palace's account with an impressive strike on the turn from the edge of Cardiff's box to give the visitors a chance to pull the game back.
It was then substitute Brandon Aveiro who snatched the goal which ultimately led to the Eagles securing a point away from home as he latched onto a Lumeka cross to put the ball into Cardiff's net.
Palace then held out well to ensure the game finished level and returned to south London with a well earned point.
