He kicked the ball away and got sin binned.
I do believe that was the top and bottom of it. Poor behaviour but he has apologised to the team who effectively had to pay the penalty for him.
Talk of anything else is daft, many players who kick the ball away get nothing during a match other than a penalty or 10 meters.
Bans and fines are for foul play or cheating not displays of petulance.
Saints discipline their players for swearing at crowds hence Eastmonds suspension. Comparing kicking a ball in frustration and Swearing at the crowd is just comparing 2 different things entirely and trying to compare an act against someone else, to an act that is self contained. It's not like he launched it at a player, an offical or a fan.
