They shed the mitts after Marsh knocks Alex Zhamnov off the puck, and Cummins steps in to defend his teammate.
It his nothing but a toe to toe war. Hard, flush punches landing from each, at least, 13 a piece by my count connect to each other. Both guys land punches on the other, sending the helmets flying. Eventually they tire out and get in tight and get against the boards as the linesman come in and break things up.
Great fight. Lots of respect shown from both guys.
