Adelaide will not field a team in the SANFL competition after being advised that no AFL-listed players are permitted to take part in second-tier leagues this year.

Crows Head of Football Adam Kelly said the Club would now look at other ways to support player conditioning and development.

"This decision is understandable given the AFL protocols are aimed at ensuring the return of elite-level matches but it is nonetheless a disappointing outcome for all of our players, coaches and staff,” Kelly said.

“We will certainly miss being a part of the State League in 2020 and we will turn our attention to how we can best support our players without the benefit of match play."
