The tension and frustration surrounding the Canucks came to a head during practice on Thursday as a fight broke out between players. The altercation reportedly involved defenseman Willie Mitchell and winger Mason Raymond. Mitchell ran at Raymond during a drill and when Raymond came back at Mitchell in the corner, Mitchell punched Raymond in the head and cross-checked him on the shoulder. The fracas drew several players and coaches, and tough defenseman Shane O'Brien skated to Raymond's defense and challenged Mitchell to fight before tempers calmed.
