Port Adelaide have confirmed that young gun Lachie Jones will miss the remainder of the season as he prepares to undergo hamstring surgery.

The young defender missed three games for the Power after he suffered a hamstring injury in Round 16 but returned in time for his side's Round 20 clash against Collingwood.

The club has revealed that Jones re-injured his hamstring in the narrow loss to the Pies and is now set to have surgery to repair the tendon in the coming days.

20-year-old Jones was drafted with Pick 16 in the 2020 AFL Draft and made his debut in 2021, going on to play six games in his rookie season and 14 in 2022.

Though the Port fan favourite won't feature again for Port for the remainder of this season, the Power are confident Jones will be right to go for 2023's pre-season.

Jones joins Jake Pasini on the injury list, with the young defender also ruled out for the season after suffering a knee injury earlier in the year.

Port will also be without Todd Marshall for this weekend's clash after the young forward entered health and safety protocols, expected to be replaced by Brynn Teakle for his second game at senior level.

Skipper Travis Boak is also expected to feature in the Saturday night clash, revealing to Nine News Adelaide that he'll line up for the Power despite having a broken left hand.
