Major fouls in lacrosse include rough or dangerous checks, blocking, charging, illegal contact, dangerous shots, and violating the three second rule in the attack area. There are 25 types of major fouls outlined in the rulebook. Some major fouls, like checking an opponent's head, require a mandatory yellow card. After a major foul, play is set up differently depending on where the foul occurred, with the offending player standing 4 meters behind the player with ball possession.
