The Sydney Swans have made one late change to their side to face Richmond at the Gabba on Sunday afternoon. 

Defender Aliir Aliir is out of the selected side and has been replaced by Robbie Fox.

Assistant Coach John Blakey said it was important for the key defender to get some form back in the reserves.

“Aliir has just struggled with a bit of form and we just want to get him back to his very best form,” Blakey said.

“We obviously face a few issues with our height both down back and in the ruck but we think that we can manage that.”

Fox has played two matches this season and returns to the side after missing last week’s match against West Coast.

Exciting young duo Dylan Stephens and Chad Warner will make their debut against Richmond.
