Brent Harvey is confident Drew Petrie will be fit to take on St Kilda on Saturday night despite the key forward wearing a guard on his left wrist at training on Monday.

Harvey, on the eve of his record-breaking 427th game, said Petrie would be doing everything to play.

"Knowing Drewy, he'll be icing that at two in the morning, four in the morning, six in the morning. He does everything right," Harvey said after training.

"He's probably just making sure that's he's going to get up this week.

"I'm not even sure what was wrong. It might have been a little bit inflamed or a little bit swollen, so he's just got a compression bandage on it.

"I don't think he'll miss this game."
