How many minor penalties can a player serve at one time?

In hockey, a player can serve one minor penalty at a time. When a player is assessed a minor penalty, they must sit in the penalty box for two minutes, during which their team plays short-handed. If the opposing team scores a goal during those two minutes, the penalized player is released from the box early.

While a player can accumulate multiple minor penalties over the course of a game, they cannot serve more than one minor penalty simultaneously. Additional penalties serve as a continuation of infractions but result in the subsequent player serving their penalty only once the first penalized player has completed their time in the penalty box. This rule is designed to maintain fairness and pace in the game, ensuring that teams aren't overloaded with players in the penalty box at the same time.
