We present a 23-year-old male professional Australian Football player who experienced a total of seven sports-related concussions between May-2015-March-2019, not associated with loss of consciousness (see supplementary materials for clinical details). Advanced brain imaging was performed after the latter four of these, revealing that his brain underwent a pattern of focal, but transient, increases in T2 relaxometry following concussive events.
