Concussions in rugby have been facing increased scrutiny in recent years because of growing concerns about player welfare and the long-term health consequences associated with head injuries.
Scientific studies have highlighted the connection between repeated head impacts and neurological disorders, such as chronic traumatic encephalopathy (CTE).
High-profile cases involving retired rugby players and their struggles with cognitive decline and mental health issues have garnered significant media attention.
Last month a British law firm announced nearly 400 ex-players including former All Black Carl Hayman and England international Steve Thompson, have joined a class action lawsuit against the governing bodies of the sport.
Research in England revealed about 20 per cent of professional rugby players suffered at least one match concussion in the 2018-2019 season.
