As Ilya Bryzgalov was covering a puck, Crosby was cleared away from the goal by the Flyers as he was swatting at the covered puck.
A scrum developed behind the net, during which Claude Giroux grabbed at Crosby with linesmen separating the players. Eventually the two players were separated from the group, in open ice.
Giroux had both gloves off and was grabbing onto Crosby. Crosby had his right glove off and was grabbing onto Giroux.
With the two doing nothing more than wrestling, a linesman came in to separate them. Crosby threw two punches at Giroux after the linesman came to the area, a typical cheap shot from the Pittsburgh captain.
He had five seconds to punch Giroux when nobody was between the two players, but waited until someone was separating the players. The linesman was able to stop the action once the players fell down to the ice.
The players were given fighting majors.

The players were given fighting majors and game misconducts for being involved in a secondary altercation.
