A bench minor penalty is like a minor penalty in that it calls for the offending player to serve two minutes in the penalty box. The offender's team will be short-handed, or down a player for 5-on-4 for two minutes. The other team is said to be on a power play and has a strong chance of scoring a goal. After the two minutes are up, the offending player can return to the ice to bring his team to full strength. If a goal is scored during a bench minor penalty is being served, the penalty clock will end and the player can immediately come onto the ice.
Here is a list of bench minor penalties in ice hockey with examples:
If a bench minor penalty is called on a player and there are already two other players on his team serving penalties, the penalty clock will not start ticking until at least one of the other penalties has expired. However, a substitute can take his place on the ice. A team cannot have fewer than four players on the ice (one goalie and three skaters).
If a goal is made on a power play while a bench minor penalty is being served, the penalty clock will immediately expire and the offending player may return to the ice. The offending team will return to full-strength once the penalty expires.
Sometimes calling penalties can be more complicated when multiple players on both teams are called for penalties at the same time.
In this case, the referees will determine the on-ice strength of both teams by canceling out as many minor penalties, bench minor penalties, double-minor penalties, major penalties, and match penalties as possible.
