A few years ago, the Panthers traded Jonathan Huberdeau in order to get Matthew Tkachuk. Such a personnel move was made to change the dynamics of the Panthers. General Manager Bill Zito wanted to add some grit to his lineup to win the Stanley Cup.

Matthew Tkachuk did not play for the United States in the third period or overtime against Canada in the 4 Nations Face-Off championship game on Thursday, and it's unclear how his injury might affect his return to the Florida Panthers when the NHL season resumes.

It was Tkachuk who ignited the fireworks at the start of the United States’ 3-1 win against Canada on Saturday in Montreal, fighting Canada forward Brandon Hagel at puck drop. This after he scored twice in a 6-1 win against Finland in the tournament opener for the U.S.
