PORT ADELAIDE captain Tom Jonas has been ruled out of Saturday’s match against North Melbourne at Blundstone Arena after entering the AFL’s health and safety protocols.

Martin Frederick will replace Jonas in the selected 22 to face the Kangaroos, while Miles Bergman has been added as an emergency.

The medical substitute will be named an hour before the first bounce at 1:40pm ACST from among the emergencies list, which also includes Ollie Lord, Taj Schofield and Orazio Fantasia.

Fantasia has not featured at AFL level in 2022, since having knee surgery in February.
