Collingwood has promoted emerging defender Jack Madgen to its primary list in place of injured backman Lynden Dunn.

Madgen was previously a Category B rookie. This meant that, unlike the club’s Category A rookies, he could not play an AFL game unless promoted.

The 25-year-old South Australian, who spent four years playing college basketball in the United States prior to being signed by the Magpies, has enjoyed an impressive season in the VFL.

He was named third-best player in the Pies’ VFL win over Essendon last weekend after tallying 21 disposals and three rebound-50s.

He is now in the frame to make his AFL debut in the coming weeks.

Dunn was ruled out for the rest of the season after suffering a serious knee injury against Gold Coast at Metricon Stadium in round 15.

He had been in career-best form prior to being injured.
