"We recently became aware of accusations of improper professional conduct against Bob Murray," the Ducks said in a statement. "After internal review, we enlisted Shephard Mullin to perform an independent investigation. Upon recommendation from their initial findings, we have decided to place Bob on administrative leave pending final results.
"In the interim, vice president of hockey operations and assistant general manager Jeff Solomon will assume the role of interim general manager. We will have no further comment until the investigation is complete."
Murray joined the Ducks as senior vice president of hockey operations in 2005 and was named general manager Nov. 12, 2008. The 66-year-old was GM of the Chicago Blackhawks for three seasons from 1997-1999 after working for two seasons as Chicago's assistant GM under Bob Pulford.
Murray played 1,008 NHL games as a defenseman during 15 seasons with the Blackhawks and scored 514 points (132 goals, 382 assists).
Anaheim is 511-357-123 in 14 seasons with Murray as GM, including 6-4-3 this season.
Murray was voted NHL general manager of the year in 2014 after Anaheim went 54-20-8 and finished first in the Pacific Division before losing to the Los Angeles Kings in seven games in the Western Conference Second Round in the Stanley Cup Playoffs.
Murray coached the Ducks for final 26 games of the 2018-19 season after firing Randy Carlyle. They went 14-11-1.
