JOSH Jenkins' season is over but he will learn on Sunday afternoon whether he'll require surgery to fix his fractured ankle.
 
The Adelaide forward landed awkwardly in a marking contest in Saturday night's loss to Fremantle with his ankle trapped beneath his 104kg body.
 
Crows football manager Phil Harper said the injury would sideline Jenkins for at least three months – even without surgery.
 
The silver lining of the injury was that it wasn't a knee injury.
 
"Josh was down having breakfast this morning, he's OK – while his foot's up he's fine and when it's down it's not so good," Harper told radio station Triple M.
 
"He's got a fractured ankle, whether it needs surgery or not we'll wait until he sees the doctor this afternoon when he gets back to Adelaide.
 
"Hopefully he doesn't [need surgery] but even if he doesn't it's a three-month exercise."
 
Harper said Jenkins would be ready to start pre-season on time.
 
On the back of Kurt Tippett's departure from the club and Taylor Walker's knee injury earlier in the season, Jenkins' ankle injury is a third blow to the Crows' forward stocks.
 
Lewis Johnston, 22, is expected to replace Jenkins for next week's Showdown against Port Adelaide after impressive SANFL form for North Adelaide.
 
Johnston recently returned from his own knee injury and collected 29 disposals and booted three goals in his second game back.
 
Last weekend he kicked another three goals in terrible conditions.
 
Harper said the door had been blown wide open for Johnston to stake his selection claim.
 
"He's a really good chance to play next week obviously so I'd be keen for him to play well [for North Adelaide]," he said.
 
"We don't play until the following Sunday so there's a seven-day break for him."
