Three men have been injured after a section of a small grandstand collapsed at a Brisbane Broncos fan day.
The grandstand wilted after several hundred people piled on to the temporary structure for a photo behind the senior team who were waiting in the change room.
As the crowd waited, a section of the grandstand at the rear gave way and several people fell as far as 2.5 metres.
The incident occurred just before 10am (local time).
"It just gave away suddenly," an onlooker told AAP.
