Watching tonights Scarlets v Ospreys game and saw something I'm not sure of. The Scarlets were comfortably pushing a maul upfield, but when the camera gave a close-up we could see a Scarlets player hooking an Ospreys players leg, which made the oppo hop back while still bound into the maul.
I don't think that maul collapsed, but if that player had tripped over, the maul would have collapsed over him, so bearing in mind 17.2(e) would the Scarlets have been liable to a PK for collapsing the maul?
17.2(e) A player must not intentionally collapse a maul. This is dangerous play.
Sanction: Penalty kick
