Soccer is a physical sport, and some contact is expected. A foul is called when contact is unsafe, unfair, or gives an improper advantage.
Legal contact includes:
Shoulder-to-shoulder challenges for the ball
Using arms for balance or shielding without pushing
Accidental contact during normal play
Common fouls include:
Tripping
Pushing
Holding
Charging unfairly
Kicking an opponent instead of the ball
Dangerous play
Many fouls are unintentional. Referees judge safety and fairness, not intent.
When a foul is called:
Play stops
The other team is awarded a free kick
If the foul occurs in the penalty area, a penalty kick may be awarded
Handball is determined by contact with the arm, not just the hand. In soccer, the arm includes the hand, forearm, and the part of the arm up to the shoulder.
A handball may be called if a player intentionally handles the ball or if a player’s arm position makes their body unnaturally bigger. Intent is not required. Referees consider arm position and whether the player had time to react.
If a foul occurs but the fouled team keeps possession and has a better opportunity by continuing play, the referee may allow play to continue. This is called advantage.
If the advantage does not develop, the referee may still stop play and award the free kick.
