Final answer:
If a player commits a penalty before other players arrive, the team will continue to play with the remaining players until the penalty expires or the missing player arrives.
Step-by-step explanation:
If a team has four players to start the game and one of them commits a 2-minute penalty before any other players on their team arrive, what happens?
In most sports, if a player commits a penalty before any other players on their team are on the field, the team will continue to play with the remaining players until the penalty expires. Once the penalty is over, the team can continue with the remaining players or wait for the missing player to arrive and substitute them in.
For example, in ice hockey, if a player receives a 2-minute penalty before any other players on their team arrive, the team will play with three players until the penalty is over or until the missing player arrives and can be substituted in.
