Lucas Browne's promoters are investigating the Australian heavyweight boxer's second positive doping result in a year, saying it is "a bitter blow" after his previous exoneration.
Hatton Promotions issued a statement saying it was aware of reports Browne had failed a test undertaken recently as part of the World Boxing Council's Clean Boxing Program.
Browne's A sample came back positive for the banned substance ostarine - which is used to aid muscle recovery - following a recent test in Australia by the Voluntary Anti-Doping Association. He is entitled to request that the B sample be examined.
This comes seven months after he tested positive for the banned substance clenbuterol following the March 5 bout against Ruslan Chagaev of Uzbekistan, which he won in a 10th-round technical knockout.
Browne, 37, was suspended by the World Boxing Association following that test but was later cleared after alleging his food was deliberately contaminated, and was scheduled to fight Shannon Briggs for the WBA's 'regular' title by the end of the year.
"Clearly the test results are hugely disappointing for the company and for Lucas himself," the statement from Hatton Promotions read.
"For a man and a team who fought so hard to clear his name following what is now universally accepted to have been a deliberate contamination of products he ingested prior to his March fight with Ruslan Chagaev, this is a bitter blow.
"Lucas was cleared of any deliberate wrongdoing a few months ago and we feel it would be somewhat unfair and incorrect for anyone to suggest that the results of his latest test bring the outcome of his previous exoneration into question."
Hatton Promotions said it would not comment further until it had conducted a full investigation, including prescribed medication and supplements, of the latest case.
"Even though he has no WBC ranking to protect and is in a position for a mandatory WBA world title fight, Lucas entered the WBC Clean Boxing Program voluntarily," the statement added.
"We do not feel that is the action of a man who wishes to intentionally take performance enhancing drugs."
