Palace stretched their unbeaten home run to four games with a 1-1 draw against Nottingham Forest.
Darren Ambrose converted a stunning 25 yards free kick for his 7th goal of the season to give Palace the half time lead, before David McGoldrick equalised for Forest three minutes in to the second period.
Neil Warnock made two changes to the line up that lost to Leicester on Tuesday by dropping Nick Carle from the squad and replacing him with Johnny Ertl, while Alassane N'Diaye dropped to the bench for Ambrose.
The home side lined up in a classic 4-4-2 formation with Freddie Sears and Alan Lee heading up the attack, Shaun Derry and Ertl in the middle, with Ambrose and Neil Danns on the wings.
On five minutes the home side had their first chance when Ambrose sized up a free kick 25 yards and drove a rising shot that Lee Camp saved well.
A minute later, Forest replied with a tame header from Nathan Tyson at the back post that Julian Speroni saved easily, while Clint Hill saw his a looping header drop on the wrong side of the bar.
Sears then almost found Danns with a cross into the box. The midfielder had not expected the ball to fall to him as it escaped the defender and it bounced into Camp's hands.
Tyson then almost pounced on a free ball in the area when the Palace defence played for offside and it wasn't given, but the ball skipped just infront of him.
But the rest of the half belonged to Palace. First Alan Lee shrugged off his marker on 20 minutes to aim a header goalward that was cleared away for a corner, before he saw a 20 yard shot deflected into Camp's hands seven minutes later.
There was reason for concern on 35 minutes when Sears was forced off with what looked like a groin strain, and he was replaced by Victor Moses.
The substitute almost had an immediate impact when he pounced onto a ball in the box, used his shoulder to take it past his marker and then, eight yards from goal, aimed a shot at goal only for Camp to pull of an amazing one handed save.
So, with the pressure building cue Ambrose. The midfielder had seen two previous free kicks from 25 yards fizz wide, but on 40 minutes he curled a beautiful effort into the top right corner.
Unfortunately the lead failed to last long after the restart as Forest restored parity on 48 minutes when a driven cross by Lewis McGugan was converted from close range by McGoldrick.
That should have been only a momentary reprieve for the away side as Moses suffered the miss of the season.
Some great work by Derry on 55 minutes down the right flank saw him to the byline where he managed to deliver an inch perfect cross for the Palace winger for a simple tap in. Instead, as he stretched for it it came off the top of his boot and screwed over the bar.
Forest had a close chance themselves to take the lead on the hour mark. A lapse in concentration at the back allowed David McGoldrick to sneak in and poke a shot at goal that beat Speroni but rolled past the post.
Camp then came to the rescue for Forest when he pulled off another super save. On 62 minutes a long ball into the box by Butterfield was flicked on by Lee and Ambrose managed to stab an effort at goal from eight yards, only for Camp to stick out a right hand and push it wide.
The Forest keeper was then struggling on 79 minutes when substitute Stern John saw him off his line and aimed a long range shot just wide of the post.
On 85 Ambrose lined up another free kick, this time from all of 35 yards. His first effort smashed into the wall but his follow up effort was driven along the floor and into Camp's hands.
The final chance fell to Palace and Camp was able to have the final say as he pulled off one final brilliant save - this time it was in combination with Morgan as John looked set to score at the near post, but he got a hand to it and pushed it round the post.
Nick Carle was dropped from the squad following Tuesday's game at Leicester and Darren Ambrose was brought in as his replacement. There was also a start for Johnny Ertl while Victor Moses was given a bench spot.
