The Blackhawks have signed winger Artemi Panarin to a two-year extension.

The Russian goal scorer, 25, would have been a restricted free agent July 1, but he has agreed to a new deal that will pay him an average of $6 million per year starting next season, his agent, Tom Lynn, confirmed to ESPN.

He's currently earning $3.5 million per season.

The Pittsburgh Penguins and coach Mike Sullivan have agreed on a three-year contract extension through the 2019-20 season, the team announced Monday.

Sullivan, 48, took over the job after Mike Johnston was fired on Dec. 15, 2015. Under Sullivan, the Penguins posted a 33-16-5 record last season and won the 2016 Stanley Cup.
