The Argentine had stepped down from his AMBC duties in July due to ongoing health issues, but was still President of the Argentina Boxing Federation.

Bisbal had been involved with AIBA since 1979 and was an Olympic referee and judge at the Los Angeles 1984, Seoul 1988, Barcelona 1992 and Atlanta 1996 Olympic Games, as well as at every World Championships between 1991 and 1997.

A member of the AIBA Executive Committee since 1998 until this year,  Bisbal was an Olympic international technical official at the Sydney 2000, Athens 2004, Beijing 2008, London 2012 and Rio 2016 Games.

Bisbal also served as President of the Argentinian National Federation from 1991 until 2014, when he was elected as AIBA vice-president.

In August, following the death of Luis Romio, Bisbal was reinstalled as Argentina Boxing Federation President.

"It’s very sad to hear about the loss of Osvaldo," said European Boxing Confederation President Franco Falcinelli.

"On behalf of the European Boxing Confederation, I would like to express my deepest condolences to his beloved family, to the Argentina Boxing Federation and to the American Boxing Confederation for the death of a sincere friend and a great manager of Olympic and professional boxing.

"It will be difficult to replace his great and qualified experience, his calm analysis of the most difficult issues, his far-sighted vision of the development processes of Olympic boxing and  his availability towards the needs of our sport worldwide.

"We will miss you and we will never forget you!

"The real tomb of the dead is the heart of the living.

"The memory of your wonderful and gentle soul will forever remain in our hearts.

"May you rest in peace."
