What will be the decision of the referee if a player throws the ball into his own goal by throw in?

Answer 1

A goal cannot be scored directly from a throw in. This is the binding rule in this instance. If a player takes a throw in and the ball crosses his own goal line between the uprights and under the crossbar, the ball has crossed the goal line. Because the Laws of the Game state that no goal can be scored from a throw in, the player taking the throw in effectively threw the ball across his own goal line. This will result in a restart with the otherteam taking a corner kick.
