I wouldn't expect much the soft Hockey fans
"these day" to know this but its most likely a Boxer's Fracture.
Boxer's Fracture Overview
A boxer's fracture is a break through the bones of the hand that form the knuckles. Some doctors use the term "brawler's fracture" rather than "boxer's fracture" because a boxer is not likely to get this injury. The less well-trained brawlers have to learn how to punch without hurting themselves.
Many Leafs fans wanted a neutered Hockey team. I hope those are happy with the results.
