David Fifita may have played his last game for Brisbane after an ankle injury ended his night in Friday's 26-12 loss to Parramatta.
The Gold Coast-bound forward will go for scans on Saturday morning to determine the extent of the injury, which was originally reported to be a low grade ankle sprain.
However, with a six-day turnaround his final game in Broncos colours is in doubt with the side set to play North Queensland at Suncorp Stadium on Thursday.
Should scans confirm a more serious injury, it will put Fifita in doubt for the Queensland State of Origin squad with less than seven weeks until game one in Adelaide.
"He'll go for scans (on Saturday)," said Broncos interim coach Peter Gentle.
"He tried to come back out.
"They said he was doing some hopping and whatever and it wasn't right, so he'll go for scans tomorrow so we'll wait and see."
Fifita came off just two minutes into the second half when Eels prop Junior Paulo fell on his lower leg while trying to make a tackle.
The incident was put on report to the confusion of both Eels coach Brad Arthur and Gentle, with referee Henry Perenara calling it a 'duty of care' infringement.
Perenara was tipped off by the bunker for the 'hip drop' tackle - which is the same charge Melbourne prop Jesse Bromwich was suspended for last month.
Once Fifita went off, the Broncos were forced to finish the game with just two players on the interchange after five-eighth Tyson Gamble went off with a head knock in the opening minute.
He is also unlikely to play the Cowboys on Thursday.
The match will be the last for former Australia and Queensland star Darius Boyd, who is retiring at the end of the season.
And aside from the emotional motivation, the Broncos will be desperate to avoid their first wooden spoon in club history if they can get a win.
"There'll be plenty of media round that all week," Gentle said.
"The boys have known quite a while when Darius's finishing point was.
"We have to send Dave off as well and that's in the balance.
"We'll be doing everything to send Darbs out a winner but we owe it to everyone to put in a really good performance at home."
