Promoter: Boxer Adonis Stevenson still in coma in Quebec

Promoter: Boxer Adonis Stevenson still unconscious in Quebec City and has not improved.

MONTREAL -- The promoter for Adonis Stevenson says the boxer remains unconscious and has not improved since doctors sedated him and placed him on a ventilator after a Dec. 1 knockout loss.

Promoter Yvon Michel said Thursday "doctors do not venture an opinion on what lies ahead" for the 41-year-old fighter. Stevenson is in intensive care at Quebec City's Hopital de l'Enfant-Jesusstill and "needs mechanical assistance to breathe."

He was admitted with a traumatic brain injury that required immediate neurosurgery. Intensive care specialist Dr. Alexis Turgeon said Dec. 5 that most patients suffer lasting effects from such injuries.

The hospital has not provided an official update on Stevenson's condition since.
