Different jersey, all bets are off.
The 2017 IIHF World Championships are under way and things got heated between Flyers teammates Radko Gudas, playing for the Czech Republic, and Claude Giroux, the captain of Team Canada.
Complete coverage of the Philadelphia Flyers and their rivals in the NHL from NBC Sports Philadelphia.
Less than 10 minutes into the first game of the tournament for either team, as part of a larger scrap between the teams, Gudas unleashed a vicious, no-look, punch to Giroux that dropped the Flyers captain with one punch.
Ouch. You can see Giroux in the background getting helped by a linesman after taking the hit. Each of them ended up with two-minute minors after this scrap.
It'll be interesting to hear after the game from both players what happened during this play.
