Video surfaces of Vince Dunn KOing NHL enforcer in tunnel during his AHL career

After the signing this 6-year old video surfaces of Dunn from the American Hockey League. Dunn was playing as a member of the Chicago Wolves at the time. After Dunn took a crosscheck to the face from Kurtis Gabriel, the two were separated on the ice, but as the two left the ice things escalated. Instead of heading to the locker rooms the players instead engaged in the tunnel with Dunn getting the best of Gabriel.

It's too bad we haven't seen this Vince Dunn in the NHL, but it's never too late.
