Cái rule đó có quy định đàng hoàng nè

It is usually an offence if a player: touches the
ball with their
hand/arm when: the
hand/arm has made their body unnaturally bigger. the
hand/arm is above/beyond their shoulder level (unless the player deliberately plays the
ball which then touches their
hand/arm)
Có nghĩa là khi tay đụng banh với outward/upward motion thì mới bị phạt. Hôm qua US bị đụng tay nhưng lúc đó tay đang co lại. In fact, she was trying to avoid the ball hitting her arm.
