Brisbane centre Kotoni Staggs has limped out of the NRL’s club training session on Sunday after injuring his hamstring.

Staggs will undergo scans on Monday but appears to be in doubt for the Broncos’ match against Newcastle on Thursday after pulling up short following a sprint.

The news is a huge setback for the under-pressure Broncos with David Fifita, Jake Turpin, Jesse Arthars and Jack Bird already sidelined due to injury.
