The condition of Canadian boxer Adonis Stevenson, hard hit by Ukraine's Oleksandr Gvozdyk on Saturday night, who was in a "critical condition", is still stable.

The condition of Canadian boxer Adonis Stevenson was still "stable" on Monday, said the hospital in Quebec where he has been treated in intensive care since Saturday night and the loss of his WBC light heavyweight title against the Ukrainian Oleksandr Gvozdyk.

"The University Hospital of Laval University confirms that he is still hospitalized in the intensive care unit and (he) is currently under controlled sedation," according to a statement from the hospital.

"His condition remains stable," said the University Hospital of Quebec.

Neither the CHU nor Stevenson's manager, Yvon Michel, commented on the information given by several Quebec media that the boxer was plunged into an artificial coma after his fight lost Saturday against Gvozdyk.

The manager announced Sunday morning that his boxer was "in critical condition in the intensive care unit".

"A concussion?"

"I spoke with the people at the hospital, he was confused when he arrived, we feared a concussion, which is very disturbing," his manager told the post-match press conference. Stevenson did not show up.

The boxer, who has not ventured out of Canada for more than seven years, put his title won in June 2013 against the American Chad Dawson for the tenth time. He was dominated almost from start to finish by Gvozdyk, and their duel was stopped by the referee on the 11th of 12 occasions.

The Ukrainian, London 2012 Olympic bronze medalist, made the difference thanks to a series of strokes that stuck Stevenson in the ropes and sent him to the mat, before the intervention of the referee.

The CHU asked worried fans and the media "to allow Mr. Stevenson's relatives to go through this ordeal in privacy."
