Corey Harawira-Naera will be sent for more tests in the coming days in an attempt to clarify why he had a seizure on the field, but the good news is Canberra Raiders medical staff have all but ruled out a heart condition as the reason.
In an update that has come somewhat as relief to Raiders players and staff, an investigation of incidents during the game points to head trauma as the most likely reason behind Harawira-Naera's scary episode.
Raiders doctors have been working with staff at Westmead Hospital to search for answers after the second-rower was rushed to hospital on Saturday night.
