Port Adelaide midfielder Ollie Wines is being investigated by the AFL for a possible breach of their COVID-19 protocols.

On Wednesday night, Wines conducted an interview with Channel 7 in Adelaide at his house. Restrictions state that players must be interview at their clubs or online via Zoom or other social media platforms.

Journalist Caroline Wilson believes Port Adelaide knew about the interview, but not that it was being conducted at Wines' house.

"This interview - and the Port Adelaide Football Club have confirmed this - is in breach of the COVID-19 protocols," Wilson told Footy Classified.

"Every player is told that - and Ollie Wines has a side-deal with Channel 7 - if you're going to an interview, it has to be either at the club or via Zoom or whatever form of social media. That has been broken.

"Port Adelaide are not happy. They knew about the interview, but they didn't know it was going to happen at Ollie Wines' houses.

"I've got absolutely no idea [if he's going to play in the Showdown], but Ollie Wines, I think, was told. he knew the rules, so we'll see."

On radio, Kane Cornes provided an update on the situation.

"I can give you an update on the Ollie Wines situation. He certainly won't be going to the club this morning and Port Adelaide are just waiting for the AFL to give them word on the allowances for Ollie of going back to training," Cornes told SEN SA Breakfast.

"If there's been a safety breach with coronavirus, the last thing the club would want to do is send Ollie back to the club and then have [him] mix with the group and then all of a sudden the whole group is going to have to isolate.

"Right now this morning as his teammates are going back to training, Ollie will be staying at home until the club gets word from the AFL about what they're allowed to do in this situation.

"It gets tricker by the day when we [are] talking about quarantine and a big game on Saturday."

A crowd of 2000 people will be in attendance for the Showdown as COVID-19 restrictions ease in South Australia.
