'Fragile' And Tearful Shayna Jack Walks Into 'An Absolute Storm'

An ashen-faced Shayna Jack has arrived at Friday's ASADA meeting.

The 20-year-old swimmer denies knowingly taking the muscle-building substance Ligandrol, which was found in her system and which she claims must have been present in a supplement which she took.

The Brisbane-based freestyle specialist is seeking to clear her name, after testing positive shortly before the recent World Swimming Championships.

At today's meeting, it will be revealed just how much of the banned substance was in her system, while the swimmer will list everything she was consuming -- including food and supplements -- at the time of her test in June.

There were strange scenes upon Jack's arrival, when her taxi didn’t know where to stop, and did a lap of the block before she got out, according to 10 News First reporter Georgina Hill, who is on the scene.

"She arrived flanked by her mother and her legal representative, looking very fragile. Her mum was clutching her arm and she walked into an absolute storm," Hill told 10 daily.

"She made no comment to the media."

The meeting is expected to go for about two hours, but it is expected to take days or even weeks for ASADA to announce penalties. Jack faces a mandatory ban of four years if found guilty.

More to come.
