It’s not every day a former UFC champion stops by to watch training.

But, on Tuesday morning, Polish mixed martial artist Joanna Jędrzejczyk was on the sidelines at West Lakes with a footy in hand.

The 31-year-old athlete watched Adelaide’s main training session before undertaking a tour of the facilities.

During training, she posted an image to Instagram of herself “taking a grab”.

Before she departed, co-captain Taylor Walker presented Jędrzejczyk with her own Crows guernsey with the No. 13 on the back.

Jędrzejczyk was not the only international sports star to get behind the Crows, with former English captain Michael Vaughan also donning the tricolours.

Vaughan, who led England to its first Ashes victory 19 years during the 2005 series, posted this image to his Instagram page showing his support for season 2019.
