USA, Canada hockey stars who fought each other throw subtle jabs ahead of 4 Nations final

Team USA 4 Nations Face-Off GM Bill Guerin joins 'America's Newsroom' to discuss the United States clinching a spot in the championship game of the tournament by beating Canada in a heated game. 

For Team USA, their three fights in nine seconds against Team Canada on Saturday night all started with a group chat.

Brady Tkachuk, who was involved in the second fight just one second after his brother, Matthew, dropped the gloves, revealed that the brothers and JT. Miller also made a group chat earlier that day and planned out their fights (Brady fought Matthew's Florida Panthers teammate, Sam Bennett).

When speaking to reporters on Tuesday, Brandon Hagel, who fought Matthew, threw a slight jab at the texters, saying he fought "for the flag" and "not the cameras."

Hagel added as a subtle shot that his Canadian teammates "don't have any group chats."

Well, Matthew caught wind of that on Wednesday and hit back with a jab of his own.

"Maybe their team doesn't like each other, then, if they don't have group chats," Matthew said.

The rivalry, which has spanned decades, is probably the hottest it's ever been, and it's only going to get hotter when the two bordering countries duke it out on Thursday night in Boston for the 4 Nations Face Off final.
