Can a defender go in the crease?

In Ice Hockey, defenders are generally not allowed to enter the crease, which is the area directly in front of the goal. However, they can enter the crease if they are trying to play the puck or if it's necessary to avoid an opposing player. If a defender interferes with the goalie while in the crease, it can result in a penalty or a disallowed goal. The rules may vary slightly depending on the league, but the general principle remains the same.
