After scoring four goals on debut last round for the North Melbourne Tasmanian Kangaroos, Munn sustained a calf injury in the final quarter of the win over the Western Bulldogs.

While the injury is considered "very minor", coach Scott Gowans says the club didn't want to take any chances with the 182cm forward.

“It’s an unfortunate turn of events for Courteney who was super impressive last week,” he said.

"It’s a very minor, low-grade strain and while we’d love to have her out there this weekend, we always take a longer-term view to our players' health and won't risk further damage.

“We expect she’ll be available for selection next week.”

The no.36 draft pick will be a major loss for the Kangaroos when they face third-placed Melbourne FC, Gowans is confident they have enough depth to replace her. 

“We believe we have more than enough depth to cover the loss of Courteney, and it provides an opportunity for someone else to come in and have an impact against Melbourne," he said.

GWS Giants midfielder Emma Swanson also joins the injury list as she is set to miss the remainder of the season with a shoulder injury.

After landing awkwardly during the teams loss to North Melbourne scans revealed that the damage to the marquee signings shoulder was worse than initially feared.

Swanson has a tear in one of her shoulder ligaments and is expected to have a lengthy rehabilitation period.

“She’ll have surgery, so she’ll do some rehab with us and stick around with the playing group," Head Physiotherapist Gemma Vale said. 

“We’re hoping to have her ready in six to nine months after the stabilisation surgery ... we’ll be looking to have her ready for the pre-season of 2020.”
