While a huge concert setup for Brooks and Dunn was taking place on the ice surface, the fireworks were going off inside the Flames dressing room.
As the dressing room doors were opened allowing the media access to the players for interviews, loud shouting was heard from the room adjacent to the dressing room where the team gym and video room is. As reporters walked closer, they found Jarome Iginla face to face with assistant coach Rich Preston engaged in a heated engage. Other team members, hearing the shouting match, ran in to break it up and the media was quickly whisked back out to the hallway.
Sounds like two guys who aren't happy about losing. Probably happens alot more than we know.
