IOC rules state that Olympians cannot place bets on the Games as it may "infringe" on the "course or result of the competition".

The IOC have today announced that the trio of boxers were found by the Disciplinary Commission to have violated rules, but found no intent to manipulate any event.

As a consequence, they have avoided the possibility of being fined, instead receiving the reprimand and being obliged to follow and contribute to various integrity educational programmes.

They will need to demonstrate they have successfully followed the programmes in order to have their accreditation validated at Tokyo 2020.

These will be organised by their National Olympic Committees (NOC), the International Boxing Association (AIBA) or the IOC.

While Conlan and Fowler were found not to have bet on any of their contests, Donnelly placed a bet on his own match against Tuvshinbat Byamba as part of a large number of cumulative bets -eight altogether.

The boxer had bet that his opponent would win, but won the contest which meant that none of the bets placed were successful.

Donnelly claimed that he had signed the various documents without reading them so was unaware of the prohibition, while he stated he had bet without intending to cheat by losing his match to win his bets.

He viewed that winning the bets would be some compensation in the event he lost his match.

Bantamweight world champion Conlan was involved in controversy at Rio 2016, with Russia’s Vladimir Niktin having been awarded victory in their quarter-final bout despite the Irish boxer having been seen by many to have dominated the fight.

Conlan then went on an expletive-laden rant in a post-fight interview with RTE, where he claimed AIBA were “cheats” and that amateur boxing “stinks from the core to the very top”.

The Irishman also vowed never to fight again for AIBA, who indicated that Conlan would face disciplinary action after he put his middle finger up at the judges.

Switzerland's Denis Oswald chaired the Commission and was joined by IOC Athletes' Commission head Angela Ruggerio and Austria's Karl Stoss in deliberating over the cases involving Conlan and Fowler.

Frenchman Tony Estanguet, the co-chair of Paris' bid for the 2024 Olympics and Paralympics, replaced Ruggiero to weigh up the case involving Donnelly.

Irish Amateur Boxing Association (IABA) President Pat Ryan claimed last month there was "absolutely" no way that the boxers from the nation did not know they were breaching rules by betting.

Both the Olympic Council of Ireland (OCI) and the British Olympic Association (BOA) have also been reprimanded by the Disciplinary Commission following today’s decision.

The NOCs were found to not have properly informed their athletes about “the content of different rules applicable to them on the occasion of the Olympic Games in Rio, as well as about the content of the contract signed with them.”

Both NOCs have been requested to ensure their teams’ preparation for the Olympics includes complete education on the prevention of the manipulation of competitions and betting on the Games, using the material provided by the IOC.

AIBA have been recommended by the IOC to ensure their rules and regulations for its own competitions are compliant with the Olympic Movement Code on the prevention of the manipulation of competitions.

The IOC also stated that the governing body have been recommended to put in place education programmes on the prevention of the manipulation of competitions and betting on the Olympic Games.

"AIBA is fully committed to the IOC Ethics Programme and supports the decision of the Disciplinary Commission in respect of the three boxers," AIBA said in a statement to insidethegames.

"AIBA will be rolling out full education programmes with the support of its National Federations and Confederations in respect of these matters going forward to ensure that all our athletes are fully aware of their obligations and responsibilities in respect of AIBA Competitions and the Olympic values."

"The British Olympic Association has been informed of a decision of the International Olympic Committee (IOC) Disciplinary Commission regarding an integrity matter relating to a member of Team GB," a BOA spokesperson told insidethegames.

"Boxer Anthony Fowler was found to have broken IOC rules relating to betting at the Rio 2016 Olympic Games.

"However, it was made clear by the IOC they were comfortable that Fowler had not bet on any bouts in which he was involved, and that there was no intention to manipulate any results.

"Fowler has been asked to undertake a mandatory education programme of the IOC, and has been severely reprimanded.

"The IOC has also reprimanded the BOA and has asked the National Olympic Committee to ensure further education on matters of integrity are provided to athletes ahead of future winter and summer editions of the Olympic Games.

"The BOA is disappointed the IOC has failed to recognise their extensive work in this important area and the clarity of its team contract in relation to matters of integrity.

"The BOA will not appeal against this decision and will continue to work with all Olympic sports to ensure educational messages around betting are prominent in ongoing communication to athletes."

When contacted by insidethegames, an OCI spokesperson said "we expected the standard response and we got it."

Several measures were put in place to protect the integrity of the Olympic Games in Rio by the IOC, including a fully operational Joint Integrity Intelligence Unit implemented in collaboration with experts from the Organising Committee.

There was also a reinforced Integrity Betting Intelligence System, while the Olympic Movement Code on the Prevention of the Manipulation of Competitions was implemented for the first time.
