STAR Adelaide midfielder Rory Sloane will miss at least another fortnight after reinjuring his troublesome right foot at training.

An innocuous incident at the club's main session saw Sloane suffer a Lisfranc ligament strain, which the club said in a statement is "slightly different" to his original injury.

The 28-year-old had scans on Thursday and consulted a surgeon, with a decision made for Sloane to rest.

INJURY CRISIS AT ADELAIDE: Are Crows hamstrung by training regime

He hasn't played since Adelaide's round four loss to Collingwood.

"At this stage, Rory will miss the next two games before we reassess his situation," Crows head of football Brett Burton told afc.com.au.

"Surgery is not required but our medical advice suggests the best course of action is to rest and recover.

"Rory is one of the most professional and diligent players at the club and will do all he can to return as quickly as possible."
