So in my son's U17 match, a kid deliberately pulls on the shirt of an attacker to try to stop the attack but the attacker shakes him off. The referee yells advantage. The same defender catches up to him a second later and again tugs on his shirt. The attacker shakes him off. Again, the referee yells advantage. The attacker passes the ball to a teammate who shoots and misses for a goal kick. During the stoppage of play, the referee tracks down and gives the defender a yellow card. So immediately I thought the referee was wrong, but it made me wonder....could there be a reason to give a YC here? Could he have looked at it as something other than SPA, such as persistent infringement or something or do you think the referee was just plan wrong to give the YC for SPA. Thanks.
