Bob Murray has resigned as executive vice president and general manager of the Anaheim Ducks, the team announced on Wednesday. The move is effective immediately, and Murray will enroll in an alcohol abuse program.

The decision was made one day after the Ducks placed Murray on administrative leave pending an internal investigation into allegations of improper professional conduct. Anaheim has not specified when these complaints were made, or how many people have come forward.

Assistant general manager Jeff Solomon has taken over as interim GM, as the franchise prepares to begin a search.
