Matthew Tkachuk is unlikely to play against the Seattle Kraken on Saturday (6 p.m. ET; KHN, SCRIPPS, KONG) because of a lower-body injury. The forward was injured while playing for the United States at the 4 Nations Face-Off.

The USA star appeared to get injured at some point in the third period of the round-robin game against Canada at the 4 Nations Face-Off. Tkachuk took a few shifts in the early parts of the frame, but he did not appear the final 12 minutes of the game.

Off, Team USA star Matthew Tkachuk voiced a strong message to head coach Mike Sullivan and his teammates, along with a warning to the rest of the teams.

It looks like both Matthew and Brady Tkachuk will be good to go for Thursday’s 4 Nations Face-Off championship.

The younger Tkachuk brother has been stellar for Mike Sullivan's team at the NHL international tournament. The Senators captain posted two goals in the USA's opening win over Finland, and then dropped the mitts with Sam Bennett against Canada in the opening seconds of the game.
