The International Olympic Committee has confirmed male boxers will be allowed to fight at Rio 2016 without headguards after not opposing a proposed rule change.
The International Boxing Association had asked for the Olympic tournament to be brought into line with its own new competition rules for amateurs, which were introduced three years ago.
Since then, boxers have fought without the protective skullpads at two World Championships and also the 2014 Commonwealth Games in Glasgow.
AIBA's medical commission has offered scientific studies as evidence there were now fewer concussions.
Following Tuesday's decision by the IOC executive board not to offer opposition, the same set-up is clear to come in for the summer Games in Brazil.
IOC spokesman Mark Adams said: "AIBA provided medical and technical data that showed the number of concussions is lower without headgear. They have done a lot of research in the last three years. The rule will go ahead for Rio."
Olympic boxers have been using protective headguards since the 1984 Games in Los Angeles. Women's boxing featured at the Olympics for the first time in London 2012, and female fighters will continue to wear headguards.
