7NEWS reporter Xander McGuire revealed scans on Monday revealed the 31-year-old broke his leg.

“Scans have indicated a broken leg for Nick Vlaustin - meaning his stellar 2025 season has officially come to a close,” he tweeted.

“The 31-year-old is on crutches and in a moon boot after landing awkwardly and being subbed against North Melbourne yesterday.”

Coach Adem Yze had already confirmed the star defender’s season would be over, but was unsure of the extent of the injury.

“It looks like its either a syndesmosis (injury) or a fractured ankle. His season is done,” Yze said after the match.

“He was a bit frustrated that he couldn’t help in the second quarter and his first impact, he went back with the flight and that’s the reason why he’s such a good player, the courage to go back with the flight.

“He is a great leader of our footy club and he’s had a great season and unfortunately he’s going to miss next week and can’t finish off the season with the boys.”

Vlastuin enjoyed another standout season for the Tigers, averaging a tick under 20 possessions and six marks again.

The veteran has never made the All-Australian team in his career, but will be in the mix this year.
