Early last year, I commented on reports that eight former International Rugby players who had been diagnosed with dementia, were planning to present a letter of claim to the governing bodies for failing to protect their players adequately against the risks of neurological impairments. 

Today, it has been reported that the case looks destined for the courts in a class action involving more than 185 rugby union players, making it the largest "class action" lawsuit to be launched outside of the United States. 

Concussion has been a huge focal point within Sport and Sports Medicine for the last few years, with huge steps being taken by governing bodies to reduce the risk of concussion and to help in the detection, diagnosis and recovery. 

This action will inevitably have a significant impact on Rugby and sport as a whole.
