ADELAIDE forward Josh Jenkins won't require scans on his right knee, with the club confirming he no suffered structural damage when it hyper-extended against St Kilda on Sunday.

Jenkins sent an almighty scare through the Crows camp in the opening term when he landed awkwardly on his right knee after being pushed over the boundary line by Saint Rhys Stanley.

The forward's knee buckled in an incident reminiscent of the way Taylor Walker tore his ACL three weeks ago.

Jenkins was able to play out the game with a strapped knee, but coach Brenton Sanderson admitted after the match that his heart was in his mouth when the big man went to ground.

Sanderson initially said Jenkins would have precautionary scans to make sure there was no damage, but the club confirmed on Monday morning that doctors had deemed them unnecessary.

The news would be a huge relief to Sanderson, who has lost three key forwards since last season - Kurt Tippett to the Sydney Swans, Taylor Walker to a season-ending knee injury and Lewis Johnston to a long-term knee injury.

Jenkins has been in good touch since winning greater responsibility in Walker's absence, booting 8.11 in his last three outings.

He will be eased through the early part of this week to allow the swelling in his knee to subside, but is expected to be available for next weekend's clash against North Melbourne.
