Wrestling's bid to be reinstated as an Olympic sport has been dealt a blow after its international federation was officially warned for breaching rules.
The sport is
vying with squash and baseball/softball
to be included in the 2020 Games in Sunday's vote after being
dropped by the International Olympic Committee (IOC)
"An official warning was sent on Friday 30 August," an IOC letter to the three international federations stated.
"The matter is now considered closed."
It added: "It was recently brought to our attention that the wrestling federation and an organisation supporting them engaged in activities that were not in line with the 'Rules of Conduct for the international federations seeking inclusion in the Olympic programme'."
Wrestling is the front-runner to win the contest, which will be decided during the IOC's 125th session in Buenos Aires.
IOC members will also
decide on Saturday which of Istanbul, Tokyo and Madrid will be the host city
for the 2020 Olympics and Paralympics.
