Scans have revealed that Sharks hooker James Segeyaro sustained a broken arm against the Melbourne Storm and is to undergo surgery later on Tuesday.
Segeyaro is at this stage set to miss six weeks of NRL action.
Having previously broken the same arm, the injury is a setback from Segeyaro who has been impressive off the bench in his three outings in 2017, including scoring the only try in last week's win over Melbourne.
