A player may only stop the ball with the stick, the chest, two feet together or one foot on the ground. Only the goalkeeper may use his hands, but only with an open palm since he is not allowed to catch it. Playing the ball with the head constitutes a foul whether intentional or not, as it is considered dangerous play. Other examples of dangerous play, which will be penalised, are a player, while grounded, playing the ball, or a player recklessly swinging the caman in the air in a way which might endanger another player.
