South Sydney back-rower Angus Crichton vomited four times throughout Saturday night’s game as he continues to struggle to overcome a virus that has almost left him without voice for the past 10 days.

Crichton said he released "three or four projectiles in the in-goal" in what was an inspired 80 minute performance.

The NSW Origin representative, who is also believed to have infected Souths stars Greg Inglis and Sam Burgess in the lead-up to the one-point win against the Dragons, struggled to talk after the game.

His voice was hoarse from the virus he copped in the lead-up to the Melbourne final in week one, but insists he was always going to play.

"I’ve been crook the last couple of weeks," he said.

"I’m a bit rattled but mate, I was never going to miss that game. We got the win and that’s all that matters. I’ll worry about how I’m feeling later.

"I was vomiting out there tonight. I’ve been seeing a doctor trying to get right. Hopefully I will be in better shape next week."

South Sydney even contemplated sending him to Melbourne on a separate flight to the rest of the players to avoid the virus spreading through the team.

However he was quarantined when they arrived in Melbourne, with Crichton given a room to himself while the rest of the players shared with someone else.

Souths were resigned to losing Crichton for the match against the Storm, but his commitment to the club in his final season as a Rabbitoh shone through.

"I love this team and I love this club so there was no way I was going to miss these games," he said.

"The NRL is bloody hard to play when you can’t speak, I can tell you that much."

The win against the Dragons sets up a mouth-watering preliminary final showdown against their arch rivals, the Sydney Roosters, the club Crichton will join whenever South Sydney’s season comes to an end.

"I don’t want to think like that. Right now I’m wearing the red and green and I’m a Rabbitoh," Crichton said.

"I want to leave here a winner and I’ll do everything I can to make sure that happens. The fact it’s against the Roosters means nothing. I’m here for Souths.

"Grand final qualifiers are huge in their own right, and to have that rivalry with the Roosters, we’ll be fired up in every sense."
