Florida Panthers forward Matthew Tkachuk, who has missed the past four games since suffering a groin injury during the 4 Nations Face-Off, was placed on injured reserve Sunday.

It was not immediately known if Tkachuk is on the traditional or long-term IR.

Tkachuk first experienced discomfort during the 4 Nations Face-Off, where he helped lead the United States to the tournament final. He was limited to 6:47 of ice time in the United States' 3-2 loss in overtime against Canada.

Evan Rodrigues and Mackie Samoskevich could see additional ice time in place of Tkachuk, who has totaled 57 points (22 goals, 35 assists) in 52 NHL games this season.

A Stanley Cup champion with Florida, Tkachuk has totaled 636 points (240 goals, 396 assists) in 642 career games with the Calgary Flames and Panthers.
