The defender had been playing at the Belgian club for the past five years, making a total of 43 appearances, although he had plans to move to the PSL in the near future.
KAS Eupen confirmed the news on their official website [translated]:
KAS Eupen received terrible news from South Africa in the late afternoon service. Ntuthuko Radebe, who has played for KAS Eupen for five years and also last season, has died in his home country with a car accident at the age of only 23 years. This message has shaken the entire community of KAS Eupen and has been deeply saddened.
As a graduate of the Aspire Academy Ntuthuko Radebe came with the first group of the Aspire players in summer 2012 to the KAS Eupen. Until June 2017 he was a member of the squad of the first team and in 43 games he was wearing the jersey of the KAS Eupen. His plan was to continue his career in South Africa.
The team, coaches, supervisors, all employees and fans of KAS Eupen have lost a good friend with Ntuthuko Radebe. With his kindness, his comradeship, his loyalty, his commitment, his good humour, he deserved great appreciation. Ntuthuko Radebe remains in the best memory of the entire KAS family.
KAS Eupen would like to express heartfelt compassion to his mother, his family, his friends and all who mourn him.
Thanks for everything Ntuthuko!
