"He's unwell and is still in ICU. He was put on oxygen but it is off now. We are hoping he will recover fully," Antic's son William, told PTI today.
Antic, 90, represented the country in the 1960 Olympic Games at Rome where Pakistan ended India's glorious 32-year golden run by winning the final between the arch-foes 1-0.
A centre half, Antic also was part of the hockey squad that finished runner-up to Pakistan in the Asian Games at Jakarta two years later.
After his playing days, he took up coaching and was the national coach of the Oman team that took part in the 1982 Asian Games in Delhi.
"He was the Oman national team's coach for two years," William said.
