Carlton has confirmed that young defender Ciaran Byrne's 2016 season is over due to a ruptured ACL in his right knee.
Byrne injured his knee during the Blues' loss to Collingwood on the weekend, with scans on Sunday confirming the bad news.
The 21-year-old will miss the next 12 months.
"Long-term injuries are always disappointing, particularly as Ciaran was having a really solid season so far," Carlton football manager Andrew McKay said.
"He will undergo surgery in the coming weeks and will commence his rehabilitation process not long after that.
"Ciaran is a resilient young man and will have the club's full support throughout this process."
He has played 11 games for the club this season for a total of 12 career games.
