North Adelaide forward Lewis Johnston will be assessed by the Crows' medical staff before he gets any clearance to play West Adelaide in Sunday's SANFL preliminary final.

Johnston missed last weekend's semi-final win against the Eagles due to a sprained ankle.

Roosters coach Josh Francou said he understood it was a hard call for the Crows.

"From a Crows point of view, he's their property. He's proven in the last six games that he can play at the elite level and I can totally understand their caution in allowing him to play if he's not 100 per cent fit," he said.

"I spoke to him this morning and we probably won't know until he's assessed by their doctor, which will probably be either Thursday or Friday, so we won't know til then but having said that I'm pretty confident he'll play."

West Adelaide captain Ryan Ferguson remains in doubt for the preliminary final.

Ferguson missed Sunday's semi-final loss to Norwood because of concussion.

Westies coach Andrew Collins said Ferguson was still recovering.

"Obviously we're praying to the gods for Ferg but he's still pretty crook at the moment," he said.

"He's still not running and it was a really big hit and you know it was his second concussion for the year.

"We really want Fergy out on the park, his leadership and his skills are essential to us but you're not going to put an individual's health at risk."
