Inverness defender Chris Hogg's season is over because of cruciate ligament damage to his knee, sustained in the 3-2 defeat by Dundee United.
Manager Terry Butcher said the injury was one of the worst he had seen.
"I've never had a serious injury before. It's really galling to write off the rest of the season," Hogg told his club's website.
"I'm just waiting to find out when I can have an operation so I can get on with my comeback."
A scan revealed other problems as well as the ligament damage.
The injury happened just 15 minutes into the match, during a collision between himself, Gary Mackay-Steven of Dundee United, and his own team-mate, David Davis.
"I knew right away that it was a bad one. But I just have to get on with it," said Hogg.
Inverness Caley Thistle manager
“Lots of players have come back from injuries like this and had a good career”
"I'm a strong character and I'm being helped by the backing of the club doctor and physios, and by Terry Butcher and (his assistant) Maurice Malpas, who have been tremendously supportive.
"The manager is one of the nicest guys I've met in football and he's been superb."
Butcher said he and his backroom team had been shocked by the severity of the Englishman's injury.
"It's one of the worst knee injuries we've seen. My physios have never seen damage that great before," Butcher told BBC Scotland.
"But we stand by Chris and we'll certainly make sure he gets the best treatment and rehab."
"It's really bad news for Chris as he was just starting to get back to form and back into the team," said Butcher.
"It's not nice at all. We look forward to him coming back - because he will be back.
"Lots of players have come back from injuries like this and had a good career. We're all being positive and upbeat."
Hogg signed for Inverness at the end of the 2011 January transfer window after spending six years in Edinburgh with Hibernian, where he was captain.
Since then, he has managed 22 appearances for Caley Thistle, scoring once in a Scottish Cup win over Morton.
