what is the signal for an indirect free kick
Indirect free kick The referee indicates an indirect free kick by raising his arm above his head until the kick has been taken and ball has touched another player other than the kicker or has gone out of play.[2]
Throw-in A goal cannot be scored directly from a throw-in; if a player throws the ball directly into their own goal without any other player touching it, the result is a corner kick to the opposing side.[4] Likewise an offensive goal cannot be scored directly from a throw in; the result in this case is a goal kick for the defending team.
