The Panthers have signed starting center Aleksander Barkov to a six-year extension.

The extension is worth an average of $5.9 million per season, a source told ESPN's Pierre LeBrun.

Barkov is third on the Atlantic Division-leading Panthers in scoring, with 12 goals and 18 assists in 38 games this season.

The Kings and forward Anze Kopitar have agreed to terms on an 8-year contract extension, Kings President/General Manager Dean Lombardi announced today.

The Panthers and head coach Gerard Gallant have agreed on a multiyear contract extension, the team announced Saturday.
