The Toronto Maple Leafs waived underperforming goalie Ilya Samsonov and the Buffalo Sabres ended their three-goalie rotation by waiving Eric Comrie, a person with direct knowledge of the moves told The Associated Press on Sunday.

Ottawa Senators owner Michael Andlauer has named president of hockey operations Steve Staios the team's new general manager, the team announced Sunday.

Dave Poulin was named senior vice president of hockey operations, having served in a similar role with the Toronto Maple Leafs from 2009 to 2014. Ryan Bowness, an assistant general manager with the Senators, is now the team's associate general manager.

Toronto Maple Leafs defenseman John Klingberg will have hip surgery at the end of month and miss the remainder of the season, general manager Brad Treliving announced Wednesday.
