VETERAN St Kilda defender Sean Dempster has been left out of the side to face Sydney at Lavington Sports Ground on Sunday.

Dempster played in a VFL practice match on Saturday for Sandringham, along with midfielder Blake Acres and Billy Longer, who were also dropped from the 27-man squad.

For Sydney, big man Callum Sinclair will enter the home and away season with just one competitive match at AFL level since round 19 last year after he was omitted for the clash with the Saints.

Sinclair had his 2016 campaign ended by surgery on his right knee but played against Greater Western Sydney in the Swans' second JLT Community Series match.

Defensive pair Jeremy Laidler and Nic Newman were also dropped from the squad.
