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]
Penalty (rugby) In rugby football, the penalty is the main disciplinary sanction available to the referee to penalise players who commit deliberate infringements. The team who did not commit the infringement are given possession of the ball and may either kick it towards touch (in which case the ball back rule is waived), attempt a place kick at goal, or tap the ball with their foot and run it. It is also sometimes used as shorthand for penalty goal.
