Port Adelaide will be without star veteran Travis Boak this weekend after the midfielder was forced to enter AFL health and safety protocols.

The Power confirmed on Thursday that Boak won't be available to face the Swans in Saturday's clash in what is a major blow for Ken Hinkley's side.

Hinkley confirmed to media that mid-season recruit Brynn Teakle will make his AFL debut after joining the club just 15 days ago.

Teakle ventured to Alberton Oval from East Fremantle through the Mid-Season Draft on June 1, having been taken with the eighth overall selection.

Standing at 203cm, Teakle will take on the ruck duties for Hinkley's side after the senior coach opted not to select a recognised ruckman against Richmond last week.

Teakle booted three goals from 13 disposals in the SANFL over the weekend, playing a role in the Magpies' 17-point win over Central Districts, where he also recorded 11 hit-outs, seven marks and three clearances.

The 22-year-old's inclusion will likely mean young tall Sam hayes will spend another week in the reserves.

Hinkley will also be required to cover the loss of Trent Dumont, who suffered a calf injury in the loss to Richmond.

Jackson Mead, Mitch Georgiades and Martin Frederick are understood to have gained a reprieve, with Robbie Gray managed and Steven Motlop dropped.

Port Adelaide will host Sydney at Adelaide Oval at 1:45pm (AEST) on Saturday.
