The Dallas Stars fired coach Jim Montgomery Tuesday "due to unprofessional conduct."
The team did not elaborate on the conduct in its statement.
"The Dallas Stars expect all of our employees to act with integrity and exhibit professional behavior while working for and representing our organization," Stars general manager Jim Nill said in the statement. "This decision was made due to unprofessional conduct inconsistent with the core values and beliefs of the Dallas Stars and the National Hockey League."
The 50-year-old Montgomery was in his second season with the Stars after five seasons as coach of the University of Denver.
