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.

Seth Jones impressed his Florida Panthers teammates in his debut Monday night, but it’s anyone’s guess when Matthew Tkachuk will be sharing the ice with his newest teammate.

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.
