The Brisbane Broncos are doing their best not to be distracted by the ongoing investigation into centre James Roberts off field behaviour.

Roberts is currently under investigation for an alleged assault early in the new year and after numerous similar incidents in the course of his career, its believed his career is hanging by a thread.

Broncos rake Andrew McCullough (pictured) says he’s seen no sign of Roberts being distracted by the latest allegations and the side is happy to leave it in the hands of club management if and when a decision is made about Roberts future at the club.
