MONTREAL - Hockey legend Jean Beliveau was listed in stable condition on Thursday after being admitted to hospital for unspecified tests.
A spokeswoman for the McGill University Health Centre said more information on the health of the Montreal Canadiens legend would be released as it became available.
One report said Beliveau suffered a stroke Wednesday night but team spokesman Donald Beauchamp said he was unable to confirm the reason for the tests.
He added that Beliveau's life wasn't thought to be in any danger.
The hockey great has had a number of health problems in the past.
In 2000, Beliveau was diagnosed with throat cancer after a tumour was discovered in his neck. He was treated and eventually recovered.
Beliveau has also had heart-related problems in the past and was hospitalized in 1996.
As recently as December 2008, Beliveau had to be admitted to hospital after a sudden drop in blood pressure following a friend's funeral in Montreal.
But the former Canadiens captain has been a fixture at home games at the Bell Centre in his seat behind the Canadiens bench.
He was also actively involved in the team's 100th anniversary celebrations last month.
Beliveau, 78, won 10 Stanley Cups during an 18-year playing career with the Canadiens.
Beliveau had short stints with the Canadiens two consecutive years before joining the club for good for the 1953-54 season. He retired following the 1970-71 campaign.
He spent more than 20-years as a club executive after his playing days were over.
Known as "Le Gros Bill", Beliveau was inducted into the Hockey Hall of Fame in 1972.
Last summer, Beliveau was named honorary captain of Canada's 2010 men's Olympic hockey team.
In his career, Beliveau had 1,219 points in 1,125 games, plus 79 goals and 97 assists in 162 playoff matches.
He was named to the NHL's first all-star team six times and the second team four times.
