Adonis Stevenson has severe traumatic brain injury, remains in stable but critical condition

Adonis Stevenson suffered a severe traumatic brain injury following an 11th-round knockout loss to Oleksandr Gvozdyk last week.

That's according to an update from Dr. Alexis Turgeon, the physician at Enfant-Jésus Hospital in Quebec City where the 41-year-old former world light heavyweight champion has remained since losing the title.

Stevenson was in critical condition, but his situation was changed to stable but critical on Sunday. Stevenson's family allowed Dr. Turgeon to issue a statement on their behalf.

“After a boxing event on Saturday night, Mr. Stevenson was admitted to Hôpital de L'Enfant-Jésus following an altered level of consciousness from a traumatic brain injury," said Dr. Turgeon.

"Mr. Stevenson underwent surgery on the night of Saturday to Sunday. He has since been admitted to the intensive care unit. He suffers from severe traumatic brain injury.

“His situation is still stable under the circumstances, but critical,” said Dr. Alexis Turgeon, a specialist physician in intensive care medicine at Hôpital de L'Enfant-Jésus of the CHU de Québec-Université Laval.

“His condition requires mechanical respiratory assistance, deep sedation, and specialized neurological monitoring. It is too early to comment on Mr. Stevenson’s long-term prognosis," Dr. Turgeon continued.

“I urge the media to be very cautious about distributing medical information that does not come from an official medical source."
