Murray was the General Manager of the Florida Panthers from 1994 through New Year's Eve of 2000. After the Panthers won the Eastern Conference Finals in 1996, he was named the NHL's executive of the year.
He also replaced Doug MacLean as coach for the majority of the 1997-98 season.
The Senators organization issued the following statement:
"Mr. Murray is undergoing further testing and will begin treatment immediately for this condition as prescribed by the team’s doctors in collaboration with specialists.
Mr. Murray’s treatment schedule may require him to be away from the Senators office periodically. During his periodic absence, assistant general managers Pierre Dorion and Randy Lee will be responsible for managing the Ottawa Senators hockey operations department.
On behalf of the entire Senators family, the team is asking that the thoughts, prayers and support of the entire hockey community are with Bryan and his family."
