PORT Adelaide will throw mid-season recruit Brynn Teakle straight into the deep end this week, with the ruckman named to make his AFL debut just 17 days after being recruited to the Power.

Teakle kicked three goals in his first SANFL appearance for the club last weekend, enough for the 22-year-old to leapfrog fellow youngster Sam Hayes and into the starting ruck position for Saturday's clash with the Swans.

However, Port Adelaide will be without important midfielder Travis Boak for the Adelaide Oval clash after the experienced onballer entered the AFL's health and safety protocols earlier this week.

Fellow veteran Robbie Gray will be managed, rookie recruit Trent Dumont will miss due to a calf injury, while veteran Steven Motlop has been dropped as the Power look to improve upon their 5-7 start to the year.

"There's about 900 games of experience leaving our side," coach Ken Hinkley told reporters on Thursday.

Gray has struggled with a knee injury since being hurt in the opening round, with Hinkley not placing a timeframe on his return.

"He has tried to play for the 10 or 12 weeks without training and that is unsustainable no matter how good you are, and we know how great Rob has been," he said.

"We won't put a timeframe on Robbie, just make sure he gets through the next couple of weeks of good training.

"Robbie had an absolutely outstanding pre-season and someone fell across his leg in round one in Brisbane and he just hasn't been able to get over it since then.

"All the things have been investigated and researched, whether it did or didn't need some surgery or anything like that.

"It was purely around rest ... Rob has played with some discomfort and it's just getting to a point where non-training and discomfort together are just making it too hard for him to perform at his best."

Key forward Mitch Georgiades, young midfielder Jackson Mead and rebounding defender Martin Frederick come into the side, along with Teakle, with Port Adelaide to make four changes.

Teakle, a 203cm and 97kg ruckman who can also play forward, was recruited to the Power from WAFL side East Fremantle with pick No.8 in the NAB AFL Mid-Season Rookie Draft just a fortnight ago.

Having previously trained with Essendon in the hopes of winning a Pre-Season Supplemental Selection Period spot in 2020, Teakle had averaged 14.7 disposals, 16.8 hitouts and kicked 6.4 goals from six WAFL games this season to earn his spot on Port's list.

"In my time in football I have never seen anyone get their first game within 14 days," Hinkley said.

"It's one of the great stories of the mid-season draft."

Hinkley's side is still without premiership ruckman Scott Lycett, who is battling a shoulder injury, while Hayes finished with 17 disposals and 33 hitouts after returning to the SANFL last weekend.

It meant that Charlie Dixon and Jeremy Finlayson shared the ruck burden during the side's round 13 loss to Richmond, with Teakle selected after winning 13 disposals, 11 hitouts, seven marks and kicking three goals on his Port Adelaide debut in the SANFL.
