Newcastle second-rower Beau Scott might have played his last game for the club after injuring his foot in Sunday's 38-22 loss to the Sydney Roosters.
Along with stand-in five-eighth Tyler Randell, who suffered a severely scratched eyeball, Scott didn't return to the field after the halftime break.
Interim coach Danny Buderus said scans on Monday would confirm whether the incumbent NSW backrower had made his final appearance in Knights colours.
"Beau has a foot injury and Tyler has an eye injury which looks pretty serious," Buderus said after the loss.
"There could be a break in Beau's foot so he'll get a scan in the next couple of days but he's getting all the right treatment in the moon boot."
Despite being down to 15 men for the entire second half and facing a 32-0 deficit, the Knights bravely fought back to get within ten points with ten minutes remaining.
But that was as close as the home side got, disappointing the surprisingly strong crowd of 17,718.
"I just remember there was a collective belief when we scored our second try," skipper Kurt Gidley said.
"The crowd lifted. I couldn't be more appreciative or thankful for the people who turned up and got behind us in the second half."
It was a disastrous start for Buderus' first home game as head coach, conceding the game's first six tries before getting on the scoreboard.
But the Knights legend said he took solace from their attempted comeback.
"The fighting qualities in the second half I couldn't be more proud of them that's for sure, but it's too hard to crawl anything back from that scenario," he said.
A broken foot for the 31-year-old Scott would likely rule him out for the rest of the season, ending a three-year stint at Newcastle after following Wayne Bennett out of St George-Illawarra at the end of 2012.
In 2014 he signed an extension on his contract that would've made him a Knight until the end of the 2017 season.
But earlier this year, Scott was granted a release on compassionate grounds due to his son needing medical assistance at Westmead's Children's Hospital and he subsequently signed a three-year deal with Parramatta.
