Sunday, 9 May 2021 The "concussion discussion" has been going on for a long time in sport, and the talking is far from done. Step by step, however, a combination of academic findings, rending personal testimony and legal action is creating significant change within sports where physical contact is a constant, or even the whole point. The long-running debate about whether boxing, where concussion is the gold medal outcome, should be banned, is now being extended to other combat sports such as mixed martial arts. The International Mixed Martial Arts Federation (IMMAF) was among sporting Federations to have submitted evidence online in March to the United Kingdom Government's Department of Culture, Media and Sport (DCMS) Inquiry into Concussion in Sport, the latest enquiry in this broad area.
