Dealing with a lower-body injury, Tkachuk has been ailing since the second game of the 4 Nations Face-Off when he missed the final 12:36 of a 3-1 win for Team USA over Canada. After having to sit out the final game of the round robin, Tkachuk took the ice for just 6:47 in a 3-2 overtime loss to Canada in the championship game on Feb. 20.

Florida Panthers forward Matthew Tkachuk will miss the remainder of the regular season with a groin injury, the team confirmed Monday. The Panthers placed Tkachuk, 27, on long-term injured reserve Sunday.

The Florida Panthers added defense to bolster their repeat of a Stanley Cup win. Now the question with Matthew Tkachuk put on injured reserve is whether they have another move coming.
