Teams may be required to play with fewer than five players for a period of time if they commit a penalty or multiple penalties. Players guilty of penalties must sit in the penalty box. The team that loses a player(s) to the box is called shorthanded while the team with more players on the ice is on a power play. If a player is assessed a minor penalty, he must serve two minutes in the penalty box. His team must play with one less man on the ice during those two minutes.
