Dennis Seidenberg isn't one to drop the mitts all that often. If his fight on Tuesday is any indication, that's probably a good thing for the opposition.
The Bruins defenseman more than held his own against Maple Leafs forward Colby Armstrong. Armstrong delivered a strong hit on Seidenberg, leading to the two exchanging words before electing to rumble. Seidenberg caught Armstrong with a number of blows, which got NESN's Jack Edwards a bit fired up.
