Melbourne midfielder Jai Culley will undergo a knee reconstruction after scans on Saturday confirmed he has ruptured his anterior cruciate ligament.

Culley sustained the injury to his left knee during the Friday nights ANZAC Eve clash against Richmond.

General Manager AFL Football Performance Alan Richardson said the news was a disappointing setback for the 23-year-old, who had been building strong form in the early part of the season.

“Unfortunately for Jai, scans have confirmed that he has ruptured his ACL, which will require a knee reconstruction,” Richardson said.

“It’s a really tough blow for him, particularly given the way he has been going about his footy and the consistency he has been able to build this year.”

“We have no doubt Jai will attack his rehab with the same professionalism he brings to his footy and we will ensure that he gets all the support he needs from our people through the recovery period.”
