The "very significant change" to traditional medal ceremonies in the 339 events was revealed Wednesday by International Olympic Committee president Thomas Bach.

"The medals will not be given around the neck," Bach told international media on a conference call from Tokyo. "They will be presented to the athlete on a tray and then the athlete will take the medal him or herself."

"It will be made sure that the person who will put the medal on tray will do so only with disinfected gloves so that the athlete can be sure that nobody touched them before," Bach added.

The Olympic approach is different to soccer in Europe where UEFA president Aleksander Ceferin has personally hung medals around the necks of players at competition finals in recent weeks.
