Concussion has become one of the biggest talking points within professional sport over the last five or six years, despite it being prevalent in professional sport for decades. 

Anybody working within sports medicine, sports law and insurance will be aware of the class action litigation brought against the NFL, not least because of the settlement which was reported to be c.$1bn. Chronic Traumatic Encephalopathy (CTE) has been the subject of much media attention, including a blockbuster film and more recently a documentary which touched on how CTE may have shaped the individual's behaviour. 

In the UK, it is said that eight former International Rugby players, who have been diagnosed with dementia, are to present a letter of claim to the rugby governing bodies for failing to protect their players adequately against this risk. 

This claim could have the potential to be worth tens, if not hundreds, of millions of pounds and will likely have huge impact on all team sport.
