ADELAIDE and the AFL are investigating an alleged training breach on Thursday by a group of quarantined Crows footballers in the Barossa Valley.

Sixteen Adelaide players and an assistant coach are completing a mandatory 14-day period in isolation, as per South Australia's COVID-19 regulations, after returning from interstate.

As of Wednesday, they were staying at Novotel Barossa Valley Resort in their own rooms, and had tailored fitness programs to complete at the expansive precinct but were under instruction not to leave its boundaries.

No other guests are staying at the resort, which is temporarily closed.

Rules state that AFL footballers must train in no more than pairs despite government restrictions differing between the states and territories.

AFL.com.au has confirmed an AFL investigation is underway, and a League spokesperson said competition officials would be "furious" if the breach was true.

"The AFL is investigating the reported breach of our protocols that are in place to protect the health and wellbeing of players, staff and the wider community. We have been very clear about the importance of all clubs adhering to the protocols and take this matter extremely seriously."

Crows football boss Adam Kelly said he had become aware of a potential breach of the League's training protocols in a scheduled session on Thursday afternoon.

"Players were told to complete any training in accordance with current AFL training protocols, which include not training in more than pairs and at all times maintaining social distancing, while staying at the facility," Kelly said.

"It appears this may not have happened for the entirety of a skills session and we are in the process of gathering the facts and liaising with the AFL."
