Dr Willie Stewart, the neuropathologist whose research recently uncovered a raised incidence of terminal neurodegenerative conditions among professional footballers in the 20th century, has urged governing bodies in sport to review their relationships with the controversial advisory panel the Concussion In Sport Group and any protocols they have formulated following the panel’s recommendations. Paul McCrory resigned last week as chair of the CISG after charges of multiple counts of plagiarism had been levelled at him.
In 2013 Stewart discovered the first known case of chronic traumatic encephalopathy in a rugby player and a year later confirmed CTE had been the cause of death of Jeff Astle, the former West Brom and England striker, who died in 2002. In response to an article in the Guardian about the Australian Football League’s decision to review the influence of McCrory, Stewart tweeted: “Suggest wider sport also review concussion policies informed by #CISG and their relationship with that group.”
