A defender commits a reckless tackle against an attacker after the ball has been touched by the attacker and gone out over the touchline. What is the correct decision?

THE DECISION

The offender is cautioned (yellow card) for the reckless challenge even though it occurred after the ball was out of play. However, play is restarted with a throw-in for the defending team because the referee cannot award a free kick as the ball was outside the field of play at the time of the challenge.
