Tariq Nabil, Gavin Heeroo and James Gibson have been told they can leave the club in the summer.
The trio are all products of Palace’s Academy and have featured regularly for the reserves this season. However, they have not managed to make the breakthrough into the first team, and Iain Dowie has decided not to renew their contracts when they expire at the end of the season.
"I cannot and will not take time over this and then tell them in May they're no longer required,” Dowie told the official site.
"That's not right for the players. I've spent time with them and made a decision on what I have seen in youth team and reserve games."
