York City have released defender Derwin Martina, just four days after he signed for the National League club.
York boss Gary Mills decided to release Martina after watching him play 81 minutes of a reserve-team defeat by Hartlepool, BBC Radio York reports.
The 22-year-old had agreed a deal to stay until the end of the season.
York’s official website had reported? that Derwin was the brother of Southampton player Cuco, but he has since denied that they are related.
“He is not my cousin, he is just a friend,” he told BBC Radio York.
“In my country, Martina’s a really big name so a lot of people have that last name, but he’s not my brother.”
