The Florida Panthers are working on a massive eight-year contract extension with defenceman Michael Matheson, according to Sportsnet’s Elliotte Friedman.

Matheson, 23, enjoyed a breakthrough 2016-17 campaign, recording 17 points in 81 games with the Panthers. It was the first full NHL season for the Pointe-Claire, Que., native, who was selected in the first round (23rd overall) of the 2012 NHL Draft by Florida.

He became a dependable blue liner for the Panthers last season, averaging 21:03 minutes per game.
