Geelong's top draft pick Nina Morrison will miss the rest of the AFLW season because of a serious knee injury.
Morrison, who was the AFLW's Rising Star nominee from the opening round, ruptured an anterior cruciate ligament in her right knee at training on Thursday.
The 18-year-old, the No.1 pick at last year's national draft, had scans on Friday which confirmed the injury.
Morrison is the second consecutive top draft pick to suffer a season-ending knee injury after Western Bulldogs' Isabel Huntington sustained a similar injury early last season.
Morrison dominated when making her AFLW debut last weekend, collecting 22 disposals and kicking the winning point in Geelong's win against Collingwood.
"It's obviously an extremely disappointing situation for Nina and the club," Geelong coach Paul Hood said in a statement on Friday.
"Nina is a resilient young woman and will tackle her recovery from this injury as she does everything, with a determination."
