Olympian Johnston Discloses Lingering Concussion Symptoms
Florida swimmer David Johnston says a head-on car crash three months ago left him with persistent neurological symptoms.
Updated on Nov. 6, 2026 in Swimming
David Johnston, a U.S. Olympian and University of Florida swimmer, announced on Instagram that he has persistent neurological symptoms after a serious head-on car accident that caused a concussion. He has not competed since an October 2025 dual meet against Alabama.
Why it matters
Johnston's condition removes a notable swimmer from competition with no return timeline set, and his injuries and recovery highlight the lasting effects head trauma can have on athletes. The announcement also leaves open whether he will seek a medical redshirt, which has not been approved.
The disclosure is a self-reported athlete statement rather than a medical record, and Johnston has been absent from competition for 13 months, since an October 2025 dual meet against Alabama. Whether he can return to competition and when remains unknown, and his medical redshirt request has not been approved.

Big Picture
Johnston's disclosure adds to growing public attention on persistent post-concussion symptoms among elite swimmers and other high-level athletes. His case shows how a single traumatic event outside the pool can end a competitive season and reshape an athlete's career path.
Johnston's absence removes him from the Florida lineup and any near-term fantasy or meet projections involving him. Whether he competes again depends on medical clearance and the pending medical redshirt decision.
The takeaway
Persistent symptoms after a concussion can extend far beyond the initial injury, and athletes often face uncertain recovery timelines. Readers following athletes can watch for official updates on medical clearance and eligibility decisions.
