Brisbane's representative centre James Roberts could be sidelined for a number of weeks after damaging his back early in their NRL round one loss to Melbourne.
Roberts left AAMI Park after just five minutes clutching at his back and in obvious pain had had to be assisted down the tunnel to the change-room.
Broncos coach Anthony Seibold said Roberts would be further assessed on Friday but the initial diagnosis wasn't good.
"Jimmy's not real flash to be fair," Seibold said after the game.
"He hurt a disc in his back in his first carry.
"We will see how Jimmy pulls up tomorrow and get the doctor to assess him.
"He was still in a bit of agony, he's not laying down or anything."
Kotoni Staggs replaced Roberts but the loss upset their interchange and their defensive pattern, with the Storm finding plenty of room down the left side through the kicking game of Cameron Munster.

Seibold said his team's performance in their opening round loss to Melbourne was a "benchmark for effort".
In his first match at the Broncos helm since switching from South Sydney, Seibold had to rally his troops from a 10-0 half-time deficit with his players starved of ball in the first half.
They scored two second-half tries through Corey Oates to get within four points before a late try sealed a 22-10 Melbourne win.
"We showed a lot of resilience and grit," said Seibold, who replaced Wayne Bennett.
"One thing we learnt was that that was a benchmark for effort.
"The effort was extremely high to get ourselves back in the game."
He said the Broncos didn't match the Storm in field position and possession, with the ineffective kicking game of halves Kodi Nikorima and Anthony Milford not helping.
A highlight for the Broncos was the return of Matt Gillett, who hadn't played since fracturing his neck in round five last season.
Playing at lock rather than his usual position on the edge, Gillett got through a mountain of work clocking up 50 tackles.
"He had a pretty good shift - he worked his backside off against a pretty fair forward pack," Seibold said.
The coach felt that overall it was good starting point for his team against last year's losing grand finalists.
"I'm under no illusions about the challenge in front of us," he said. "We're looking to take small steps and I felt we showed a lot of resilience and grit."
Melbourne coach Craig Bellamy says he couldn't have asked for more from Billy Slater's fullback replacement Jahrome Hughes, who finished with 218 attacking metres and a try.
"I thought Hughesy was our best player - he was outstanding," Bellamy said.
