The Columbus Blue Jackets gave contract extensions to three of its assistant coaches and added Brad Larsen to head coach Todd Richards' staff on Monday.

Associate coach Craig Hartsburg, goaltending coach Ian Clark and development coach Chris Clark received multi-year extensions.

"Our coaching staff, led by Todd Richards, has done a tremendous job and we're pleased to extend the contracts of Craig, Ian and Chris and to add a very bright young coach in Brad Larsen to the staff," general manager Jarmo Kekalainen said in a statement. "We believe our coaching staff is as strong as any in the NHL and that they will continue to play pivotal roles in the development and success of our team moving forward."

Richards signed an extension in May after the Blue Jackets went 43-32-7 and earned a spot in the playoffs this past season.
