Adelaide defenders Kyle Cheney and Luke Brown have been cleared to play on Saturday night after completing final training.

“They were fine,” Crows assistant coach Scott Camporeale told the media on Friday.

“They did some stuff yesterday (Thursday) and got through today and they’re all ready to go.”

Camporeale and the Crows are wary of the experience North brings into the sudden-death match, having won four finals in the last two seasons.

“Across the board they’ve got finals experience, they’ve played in the last couple of prelims.

“They’ve got a hard and tough midfield, which generally helps you in finals.

“They’ve got some power forwards, so we’ve got to restrict their supply through the middle of the ground and hopefully put their defenders under a bit of duress.”

West Coast's shock loss to start the finals series has the Crows on guard, regardless of their external status of favourites.

“History says in finals anyone is a chance," Camporeale said.

"It's a 50-50 ball game and if you allow the opposition to play how they want to play, it's going to be very difficult.”
