St Kilda has named its 26-man extended squad ahead of Sunday's match against Collingwood at the MCG.

Jack Silvagni (concussion protocols) and Bradley Hill (illness) have been named to face Collingwood after missing the AAMI Community Series clash with the Bombers. Co-captain Callum Wilkie has also overcome a corked calf concern in time for Opening Round.

Silvagni joins fellow recruits Tom De Koning, Sam Flanders and Liam Ryan in the squad for their first home-and-away season appearance in the red, white and black.

Draftee Charlie Banfield is on the extended bench after impressing in his maiden pre-season campaign. 

The final team will be announced at 5:00pm AEDT on Friday.

The game will be played at 7:20pm AEDT on Sunday, and will be broadcast live on 7, Fox Footy and Kayo.
