Kiwi freeski star Nico Porteous will be out of action until January, after undergoing surgery on his knee.
Porteous, 20, who won gold in the men's halfpipe at the Beijing Winter Olympics in February, has revealed he has gone under the knife to repair his ruptured ligament.
"A month ago, I ruptured my ACL and have had surgery two weeks ago,’’ Porteous said on Instagram.
"So it's been a pretty quick process, but definitely not what I was wanting to do to end off my season."
The Wanaka native didn't offer any explanation as to how, when or where he'd injured his knee.
"Quick oil change," he wrote. "Much love."
Porteous hopes to return in time for the northern hemisphere season in January.
"I'm not going to post any gym stuff or post any rehab, it’s not something I really want to do," he added.
"It's injury and injuries are a part of freestyle skiing, and that's my personal thing to deal with."
