Track and field sprinter Jessica Peris has tested positive to a banned substance.
She is the daughter of Olympic hockey gold medallist and former Senator Nova Peris and had been on track to follow in her mother's footsteps.
There is no confirmation of what substance is allegedly involved, but Peris pulled out of the Commonwealth Games selection trials as she awaits the result of her B sample.
The substance was detected during tests by the Australian Sports Anti-Doping Authority (ASADA) with the news becoming public this afternoon.
An Athletics Australia spokesperson said they would not be commenting at this stage.
Peris, 27, was in contention for Commonwealth Games selection after setting personal bests this summer over 100 and 200m.
The athlete had been on top of her game, after a string of successes, the most recent last month at the Glynis Nunn Shield in Brisbane when she defeated star sprinter Riley Day.
In December she managed a Commonwealth Games B-qualifying time of 23.31seconds in the 200 metres event.
