Final answer:
In ice hockey, if a player on the penalty bench remains there after the expiration of the penalty, the team cannot place another skater on the ice as long as the originally penalized player remains on the penalty bench.
Step-by-step explanation:
In ice hockey, when a player is penalized and sent to the penalty bench, their team is considered to be short-handed and must play with one less skater on the ice. Once the penalty expires, the penalized player is free to rejoin the game, and the team is then entitled to return to full strength by adding another skater to the ice. However, if the originally penalized player remains on the penalty bench after the penalty has expired, their team cannot add another skater to the ice. The team must wait for the penalized player to return to the game before they can make any changes to the number of skaters on the ice.
For example, let's say a player from Team A receives a penalty and is sent to the penalty bench. While that player is serving their penalty, Team A is short-handed and plays with one less skater. Once the penalty time is up, the player is allowed to return to the game. However, if the player chooses to stay on the penalty bench for some reason, Team A cannot add another skater to the ice until the player returns.
In summary, if a player on the penalty bench remains there after the expiration of the penalty, their team cannot place another skater on the ice as long as the originally penalized player remains on the penalty bench.
