The Tyrone native is reported to have broke quarantine restrictions before the positive test.
Irish Aussie Rules player Conor McKenna is at the centre of storm in the Australian media after testing positive for Covid-19.
The Tyrone native - who plays for Essendon Bombers - is reported to have broke quarantine restrictions before the positive test.
7News has said that there is a 'false positive line of inquiry' but that it's too early to say.
The 24-year-old is asymptomatic and had returned all negative tests previously but the positive test has led to the AFL banning contact training for large groups for the next four weeks.
