St George Illawarra's back row stocks are wearing perilously thin with Patrick Kaufusi likely out of next week's NRL clash with the Sydney Roosters.
Kaufusi is considered the worst of three players knocked out in the Dragons' contentious loss to Cronulla on Sunday.
Star lock Tyson Frizell and halfback Ben Hunt also failed to finish the match, however both are expected to be available to face the reigning premiers.
"Tyson's fine. He should've just got up a bit slower and he would've been okay," Dragons coach Paul McGregor said.
"Kaufusi, no. I think he was in a pretty bad way that he couldn't come back on.
"And the other one, Benny's okay, he just got a boot to the side of the head. He'll be fine. I'd say only two of the three would be fine next week."
Kaufusi was a mid-season addition for the Dragons, having been picked up with the salary cap dispensation from Jack de Belin's suspension from the game.
His probable absence comes one week after NSW State of Origin second-rower Tariq Sims was ruled out for the final month of the season with a groin issue.
It means rookie Jackson Ford is all but certain to get a third game, while Jacob Host will come into contention for a recall.
Despite being down to 14 men for the final 20 minutes, the Dragons showed plenty of courage to level the scores late in the contest.
And while they still lost on a contentious Bronson Xerri try with four minutes remaining, McGregor was still upset with their overall performance.
"Good commitment and effort," McGregor said.
"But pushed passes, dropped balls on play one, and going down on short sides off a scrum and running out, it's not good enough.
"And even the last one, it comes to a bounce of a ball.
"Yeah okay, Wade (Graham) touched it - which is good, he's being honest about it - (but) make the stop. That's the most disappointing thing.
"We've got to improve that otherwise we won't improve."
The Dragons, already out of finals contention, finish the season with contests against the Roosters, Wests Tigers, and last-placed Gold Coast.
