Veteran middleweight Sam Soliman has tested positive for a performance-enhancing drug, according to reports.
The 39-year-old Australian defeated Felix Sturm by unanimous decision in Dusseldorf last month to set up a potential clash with IBF champion Daniel Geale.
However, German newspaper Bild has reported that the Institute of Organic Chemistry in Cologne has detected a banned substance in his urine sample.
Soliman will now attend a hearing to decide his fate, with the result being scrapped appearing to be the likely outcome.
