Newcastle centre Dane Gagai has been taken to hospital with an irregular heartbeat, with the Knights climbing off the bottom of the NRL ladder via a 30-2 win over Gold Coast.
The Saturday night, five-tries-to-none, Hunter Stadium victory was overshadowed by Gagai's setback.
The Queensland State of Origin star was taken to Newcastle hospital during halftime with the irregularity believed to have been brought on by a virus.
Five-eighth Jarrod Mullen and hard-working prop Kade Snowden were outstanding for the Knights, who broke a six-game losing run to move one win clear of now last-placed Wests Tigers who take on Brisbane on Sunday.
Mullen scored the opening try of the second half after a break from James McManus set the five-eighth up before utility Danny Levi crashed over from close range on a wet and windy night.
Newcastle went to halftime leading 20-2 after the bulk of the early action defending.
The Titans opened the scoring through a Daniel Mortimer penalty goal before the Knights scored three tries in nine minutes.
Kurt Gidley had the home side's first try when he brought down a Mullen kick before four-pointers to Jake Mamo and Tariq Sims.
Gold Coast have now lost three straight games and remain in the mix for the wooden spoon along with the Knights and Tigers.
The Titans were expected to improve with the return of representative star Greg Bird from an eight-week suspension but the NSW star was unable to make any impression.
Knights officials said Gagai needed to be assessed by a cardiologist before any update could be given.
"We'll get a little bit more of a report on what's going on with Gags when that information comes through," said Knights coach Rick Stone.
"The physio came out and said Gags is not coming back on, he's not feeling well, he might have a bit of a virus and he's getting some dizzy spells out there.
"Obviously our doctors have managed him, got him in an ambulance, and taken him up to hospital for some tests."
Gold Coast coach Neil Henry was bitterly disappointed with his side's effort.
"It was just a very poor performance. We were talking on the way down that we've conceded 68 points in two games and scored eight against sides that are below or around where we are. It's a reflection of our last two games - it hasn't been good enough," he said.
