Kelly's a blindside flanker. He got knocked out by an outside centre (shouldn't the blindside be one of the best tacklers in the team?). There was no malice involved, Banahan was running, Kelly made a poor effort to tackle him and got his head in the wrong place. You don't have to be an international blindside to know that you should go in low against big people (or anyone for that matter) It's one of the first things taught. I lol'd when I heard there would be a possible citing. It's Rugby for christ's sake.
*baby voice:
"Ooh, that guy got hurt trying to takle a 6ft7 18st guy, let's call a wahmbulance, and then lets see if we can get the big guy cited. Maybe next time he should run a bit slower and keep his arms out the way incase another player has a booboo again."
P.S: Sorry the whole citing thing has been annoying me, just needed to get that off my chest.
