There was a similar stunt a couple of months ago on one of the fox shows where they had some stooge run at Haumole 'for a laugh'.Not sure of the finer details, but I've seen clips in Sydney as well. Whether the same company etc I don't know.
The poor guy was padded up and had a helmet I think, but Haumole's tackle didn't miss, they showed slow motion of the whiplash and I was surprised the poor guy's neck didn't snap.
