Don't believe so, an uncontested scrum is just that. The ball remians with the team with the put in and play restarts. Sure a rugby ref will give youi chapter and verse shortly.
I know about scrums etc. What I'm saying is that in the league I play in, if you have to go uncontested due to lack of front row then the game is forfit. I wondered if the WC competion had a similar rule. The laws of the game are quite clear I was asking about the rules of the competition.
