St Kilda has added four names to its extended squad ahead of Sunday's clash with North Melbourne at Marvel Stadium.

Jack Higgins and Jack Bytel have been named on-field after the former was managed with knee soreness over the last fortnight, while Jack Billings and Tom Campbell have been named in the 26-man squad.

Last week's substitute Hunter Clark has been named on the eight-man bench alongside Jade Gresham, Ryan Byrnes, Liam Stocker, Dan Butler, Marcus Windhager, Billings and Campbell.

Debutant Jack Peris, who filled Higgins' role as a small forward against the Suns last week, will make way for the more experienced goal sneak and is the only confirmed omission at this stage.

Higgins' inclusion will be a welcome addition, with the 24-year-old leading the club's goalkicking tally with 27 majors across 15 games.

St Kilda’s final team will be confirmed on Friday at 5:00pm AEST.

IN: Billings, Bytel, Campbell, Higgins
OUT: Peris (omitted) 

Last week’s substitute: Hunter Clark replaced Mattaes Phillipou in the third quarter.
