Erik Gudbranson's threat toward Matt Martin reportedly caught the attention of the NHL.

Following a chippy 6-3 loss to the Toronto Maple Leafs on Saturday, the Vancouver Canucks blue-liner said Martin's "f-----g dead."

NHL executive Colin Campbell reportedly spoke to Canucks general manager Jim Benning, saying Gudbranson better stay in line when the two clubs meet again Dec. 3 or he'll face "harsh repercussions," according to TSN's Darren Dreger.

Dreger reports the issue isn't on the league's front burner, but it takes a "threat of that magnitude" very seriously.

The Canucks and Leafs combined for 171 penalty minutes in the contest, including 10 for Gudbranson and 19 for Martin.
