O'Reilly's change of mind led to 'B' test
Boxer Michael O'Reilly's 'B' sample could have been tested regardless of his wishes.
At first, it was believed that O'Reilly had decided against requesting a test of the B sample, after his first sample had tested positive for banned substances.
Instead, it was thought that the boxer would go straight to appeal, where he could have made mitigating arguments for the positive test, such as accidental ingestion of the banned substance.
However, it has emerged that there was a change of mind in his camp and O'Reilly decided to request that the B sample be tested. It is understood that the decision was made because a successful appeal could itself be challenged in turn, whereas if the B sample does not confirm the A sample's positive, then the entire test is considered as negative.
Moreover, the B sample could have been tested as part of an appeal in any case, whether O'Reilly wanted it or not.
Sources in O'Reilly's camp have insisted that he is "squeaky clean" and are confident that the B test will come up negative.
A result could be known by today - with O'Reilly's first fight of the Olympics, scheduled for Friday, hanging in the balance.
A source close to O'Reilly has said he has undergone "around 14 drug tests in the last 30 months" and has always come up clean.
