When personal contact occurs between players, the referee may call a foul if the contact is deemed unfair or excessive. This can include actions such as pushing, tripping, or holding an opponent. The referee assesses the severity and intent of the contact to determine whether a free kick or penalty should be awarded. In some cases, if the contact is deemed reckless or violent, the referee may issue a card, either yellow or red, to penalize the offending player.
