The Toronto Maple Leafs have signed head coach Randy Carlyle to a two-year contract extension but his assistant coaches will not be returning next season.

Carlyle was entering the final year of his existing contract.

Assistant coaches Dave Farrish, Scott Gordon and Greg Cronin will not be returning next season. No new assistants have been hired as yet.

Carlyle took over the coaching reins from previous head coach Ron Wilson with 18 games remaining in the 2011-12 season.

"It was important, after a disappointing end to the season and the arrival of Brendan as team president, to conduct a thorough review of the organization as we continue the work of building a winning tradition and culture for the Maple Leafs," said Maple Leafs genereal manager Dave Nonis in a statement. "That process started with the head coach, and as we analyzed it, we decided together that Randy Carlyle was the right person to lead this team. In Randy we know that we have a leader who has enjoyed a high level of success as both a player and a coach, including a Stanley Cup championship. It was important that the positives Randy brings to our team were not overshadowed by a finish to the season that we all must take responsibility for."

His most successful season was in the lockout-shortened 2013 campaign, when he led the Leafs to a 26-17-5 record and the team's first playoff berth since 2003-04.
