Concussion Return-to-Sport Steps and Combat Sports Suspensions
After a concussion, return to sport follows a stepwise strategy, and in combat sports the Association of Ringside Physicians recommends minimum suspensions after knockouts caused by blows to the head.1,5 This page shows the six steps from the latest international consensus, the red flags that need emergency care, and the suspension minimums used in boxing. It describes published frameworks; the decision to return to contact always belongs to a healthcare professional.1
Rest is short, activity comes early
Current consensus recommends relative rest for up to the first two days, and light activity such as walking is acceptable as long as it does not more than mildly worsen symptoms.1 Early activity does not mean early contact: any risk of contact, collision or falls is avoided until a healthcare professional has cleared it.1
Repeated knockouts
In a study of 30 amateur boxers, reported in a 2013 paper, cerebrospinal fluid brain-injury biomarkers were raised in more than 80% one to six days after a bout, mostly without concussion symptoms, and about 20% still had raised levels after two weeks of rest.7 In my view, repeated knockouts are a warning sign, although no specific number of knockouts is a validated medical rule.5
