Richmond midfielder Dion Prestia says injured pair Jack Graham and Nathan Broad are in good spirits but has backed any potential replacement to step up in Saturday’s AFL grand final.

Graham is in serious doubt with a dislocated shoulder, while Broad will need to recover from concussion to play.

“(They’re) both pretty good,” Prestia said.

“So obviously, the medical team will do their job during the week and we’ll just see what happens.

“But they’re in pretty good spirits today (Sunday) and we’ll see them obviously tomorrow – we’ll be back in at training – and see how they go.”

Broad and Graham attended the VFL grand final, where Marlion Pickett starred, while midfielder Jack Ross and Kamdyn McIntosh – both potential replacements – were withdrawn from Sunday’s team.

Prestia praised the efforts of Sydney Stack, who returned from ankle surgery to play in the VFL decider, and mid-season recruit Pickett.

“Obviously, Stacky’s been out for a while and he’s done an amazing recovery with his ankle. Even getting up for this week has been amazing with what he’s done,” Prestia said.

“And obviously Marlion coming in the mid-season draft has been an amazing story and such a smooth mover – he’s just a great player.

“But yeah, it’s going to be interesting to see if the two boys aren’t able to get up or if they make any changes.

“We’ll definitely have a lot that we can go to and we’ve shown this year that it doesn’t really matter who’s out there playing, We can still play our system and it works.”
