How anyone can watch that footage, and claim contact was only to the chest/shoulder is beyond me.
Rowell is visibly dazed, and if the footage continued, you could see he was still dazed 60-90 seconds after the contact.
Watching the game, he was still visibly affected, trying to gather himself, for the next few minutes.
You don't get dazed by a bump to the shoulder!!!!!
If he was a "lesser" player, and they carted him off, the outcome would have been different. But because he toughed it out a "No harm, no foul" rule seems to have been applied.
Any WC supporter claiming the right decision has been made, or feeling vindicated in their stance on this, I look forward to you cheerfully patting the MRO/Tribunal on the back, with a "Well done, you got another one right" anytime a WC player is suspended.
