Richmond coach Adem Yze has provided an update on the injury suffered by star defender Nick Vlastuin during Sunday's Round 23 loss to North Melbourne.

Vlastuin was subbed out of the game at half-time as he hobbled off the ground with an ankle injury after falling awkwardly.

"It looks like its either a syndesmosis (injury) or a fractured ankle. His season is done," Yze said.

"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."

Richmond ends its 2025 campaign next Saturday against Geelong at the MCG.
