Interesting end to a game

Refereeing a game yesterday near Manchester away team are winning 2-1 85th minute skipper from the home team jumps in two footed on an opponent makes contact and is sent to warm the showers up for the rest of them. 86th minute free kick awarded to the home side, left back from the away team is not happy and proceeds to launch the ball off the pitch so he’s in my opinion is guilty of dissent by action as opposed to delaying the restart due to his mannerism. He is sent to the sin bin. 89th minute the home team equalise. Game ends and the player who is the sin bin tries to argue that as he didn’t swear it cannot be a sin bin and he was advised that it was and if he carried on he would get another yellow and a red. Manager from away team could not get it that it was a sin bin and he felt it was not as bad as the red card challenge to which lost them the 1 man advantage they had from the red card.

Kicking the ball away can definitely be considered dissent by action depending on the manner - so the sin bin can be used.
