lol...
McManus' "shot" on Locke was a head collision, i think you'll find.
and Ta'ai should get a couple of weeks for the swinging arm. it was vicious, and got him flush while he was on the ground (it's the second shot you're looking at whilst McManus is on the ground, not the first... which was fine-ish). if you think it's the first impact that's the problem, you're looking at the wrong footage. McManus is lying on the ground, Ta'ai comes in over the top with his forearm... absolutely nowhere near the ball, and was quite blatent and ugly.
