Palace will be bitterly disappointed to come away empty handed after falling to a late defeat against Bolton Wanderers.
The Eagles' U21 side dominated large parts of the match at Selhurst Park, but conceded late on to slump to a 1-0 defeat.
But the home side will take plenty of heart from their performance, with trialist Dean Parrett and winger Jason Banton both putting in lively displays.
Bolton settled quickly and signalled their attacking intent early in the game, but it was Palace who came closest to scoring in the opening 15 minutes. Banton cut in from the left hand side and hit a powerful right-footed shot, which was palmed away by Jay Lynch in the Bolton goal after taking a slight nick off a defender.
The visitors responded well though and came close to taking the lead themselves when a long throw out by Lynch found the lively Tom Youngs on the half way line. His clever first-time lay off picked out Joe McKee who burst through from midfield before returning the ball to Youngs, but his shot was deflected wide.
Moments later a loose pass in the Bolton midfield gifted possession to former Tottenham midfielder Parrett. The 21-year-old laid the ball into the path of Banton on the left flank, but he sliced his effort high and wide.
The Eagles began to take control of the game and came close again on 25 minutes. Centre-back Alex Wynter won possession on the half way line and beat three men on a rampaging run to the edge of the Bolton box before playing in Ibra Sekajja, who fired over.
Banton again came close to breaking the deadlock five minutes before the interval, jinking infield past two defenders before unleashing another vicious right footed drive, which had to be parried onto the post by Lynch.
It took the best part of 50 minutes for Bolton to register their first meaningful effort on target, but Jack Sampson's strike from the edge of the box was easily gathered by Ross Fitzsimons.
Moments late Sampson turned provider, playing a clever reverse pass into the path of Odelusi, but he shot straight at the Palace keeper.
Bolton were a different prospect after the interval and started to play some of the football that has seen them register just two defeats in ten U21 premier League Group Two matches. When Wynter failed to clear a cross from the right, Sampson's snap shot from the edge of the box fizzed just wide of the post.
Despite the Trotters' renewed vigour, it was Palace who came close to breaking the deadlock on the hour mark. Jason Banton saw another right-footed shot charged down, but the ball rebounded to him on the edge of the box. He feigned to shoot before coolly cutting back onto his left foot and hitting a low shot inches wide of the far post.
Aaron Akuruka's cross-come-shot then had to be helped behind by Lynch, before another powerful burst forward by Wynter saw him place his shot straight at the Bolton keeper.
A classy spin and run by Parrett set up another opportunity for Banton, whose curling effort looked destined for the top corner, only to be kept out brilliantly by Lynch flying to his left.
Parrett was beginning to take control of the midfield and he was involved again in an intricate one touch move with Allassani and Kwesi Appiah, whose effort from inside the box was too close to Lynch.
Palace had dominated large parts of the second half, but it was Bolton who scored the only goal of the match against the run of play with just five minutes left on the clock.
A cross from the left by Sampson was calmly chested down by substitute Aaron Knight into the path of the unmarked Youngs, who slotted past Fitzsimons from close range.
It was a late sucker punch that visibly knocked the stuffing out of the home side and they were unable to grab the late equaliser that their performance deserved.
