St Kilda has called a media conference with president Andrew Bassat and CEO Simon Lethlean for 11.30am on Friday. 

Ratten had been St Kilda coach for three full seasons since taking over from Alan Richardson, steering the club into the finals in 2020 but missing the top eight in the following two years.
