It will be interesting to see what they decide, considering it was a carbon copy of the Taylor incident.
If Taylor would have been (rightly) banned, I wonder whether Catalan would have targeted O'Brien? Just a thought.
Surely the RFL have to act about this now. A shoulder charge that is late should be, at least, an automatic sin bin and/or one match ban. Cheap shots on half backs is surely a question of player welfare and considering that he's been stretchered off with concussion means that it is just as dangerous as contact with the head.
O'Brien getting knocked out two fixtures in a row is not good for the player, other half backs who take the ball to the line and the sport in general.
