Shin guard
A shin guard or shin pad is a piece of equipment worn on the front of a player’s shin to protect them from injury. These are commonly used in sports including association football (soccer), baseball, ice hockey, field hockey, lacrosse, rugby, cricket, and other sports. This is due to either being required by the rules/laws of the sport or worn voluntarily by the participants for protective measures.
