Final answer:
In football, the offensive player is not allowed to commit a spearing foul.
Step-by-step explanation:
In football, the player who is not allowed to commit a spearing foul is the offensive player. Spearing is a penalty in which a player uses their helmet to make contact with an opponent in a dangerous and illegal manner. This type of foul is usually committed by defensive players and is considered unsafe because it can lead to serious injuries. Offensive players are responsible for blocking and running with the ball, so they are not allowed to initiate this type of dangerous contact.
