Kangaroos defender Aiden Bonar will be sidelined for up to three months of action after sustaining a wrist injury at training last week.
The 22-year-old has endured a luckless run of injuries throughout his young career, having played just the 22 games in four seasons.
“Aiden came back to the club in great nick after the break so it’s disappointing for him,” Kangaroos football manager Daniel McPherson said.
“He suffered a slight injury to the wrist in round five this year but it wasn’t enough to sideline him at the time. He was fine heading into pre-season and had been training without any issues until an innocuous incident in a drill last week caused the old injury to resurface.
“He’ll have the surgery next Monday, and will be back into his running program shortly after that.
Bonar joined North Melbourne ahead of the 2020 season from Greater Western Sydney after six games, returning to Victoria in heading to Arden Street, where he has since made 16 appearances.
