Australian midfielder Antony Danze has had his contract terminated by mutual consent, Palace have confirmed.
The 21-year-old joined the Eagles as a free agent in 2004 and made just two appearances in red-and-blue, both in the Carling Cup.
"He did brilliantly for us in the time he was here," Iain Dowie told the official Palace site.
"We really thought he would play a big part this year. He has had a lot of injuries and a lot of niggles and it just quite didn’t work out for him."
