The Sydney Swans have made a late change ahead of tonight's clash with Adelaide.

Ruckman Callum Sinclair goes out of the final side, with emergency Toby Nankervis to contest the ruck alongside Kurt Tippett.

Assistant coach Henry Playfair confirmed for SwansTV that Sinclair had battled an infection in his foot and was unfortunately not able to prove his fitness before Saturday.

"It's not ideal, but it's a great opportunity for Toby who has been in great form and had a great summer," Playfair said.

"He has been pressing our two ruckmen anyway so it's good for him to get a chance tonight."

Nankervis has played five career games that all came last season following his debut in Round 14. His last AFL match was in Round 19 against Geelong.

Adelaide goes in as selected.
