Goalkeeper
What is the different between handball and association football?
Handball
Only the goalkeepers are allowed to move freely within the goal perimeter, although they may not cross the goal perimeter line while carrying or dribbling the ball. Within the zone, they are allowed to touch the ball with all parts of their bodies including their feet. The goalkeepers may participate in the normal play of their teammates. They may be substituted by a regular field player if their team elects to use this scheme in order to outnumber the defending players. This field player becomes the designated goalkeeper on the court; and must wear some vest or bib to be identified as such. If either goalkeeper deflects the ball over the outer goal line, their team stays in possession of the ball, in contrast to other sports like association football. The goalkeeper resumes the play with a throw from within the zone ("goalkeeper throw"). Passing to one's own goalkeeper results in a turnover. Throwing the ball against the head of the goalkeeper when he is not moving is to be punished by disqualification ("red card").
