Richmond has locked in its extended squad for Sunday's clash against Melbourne at the MCG.

Four players have been added to the squad, with veteran midfielder Dion Prestia returning from a minor hamstring injury, exciting draftee Sam Grlj coming back after being managed, while ruckman Samson Ryan and the hard-running Tom Burton have also been named after strong VFL form.

Jack Ross is the only confirmed out at this stage, due to the concussion he suffered against Carlton last weekend. 

The final team will be announced on Friday at 5pm (AEST) on richmondfc.com.au.
