There's a good reason you can't find it - because it isn't there. :biggrin:
We discussed this at a monthly meeting recently. Using your feet in the ruck is the only legal option you have. You can ruck it back if you want / can, but equally a player legally in the ruck can kick it through if he wants. The only thing you need to be aware of, is that it's dangerous play to kick it if the SH has his hands on or close to the ball. Apart from that, it's fair game - feel free to welly it downfield if you can. :biggrin:
Gents, with respect ...I disagree
I do not believe that it was ever intended for the ball to come out of a ruck by players 'fly-hacking/booting' at it :nono:
Definition " Players are rucking when they are in a ruck and
using their feet to try to win or
keep possession of the ball ...."
Rucks were supposed to be ... one side pushing the other side away from the ball [see all Lawbook pictures ]... all logic suggests the intention of a ruck was a '
adhoc'ly' formed scrummage over the ball, whereby the ball is hooked
back towards one team, not booted forwards. [as an aside .... I do not believe that kicking the ball forward in a scrum was ever envisaged as a bona-fide attempt to win possession either]
In the instance described, the player is neither
a] "trying to win" ..... nor
b] keeping
..... possession
Notwithstanding, in almost every instance , if the ball is genuinely still 'IN' then its likely dangerous to swing a boot at it, as bodies/limbs are close by.
Kicking out of a ruck is not a positive action, it's a purely negative disrupting tactic, and should be outlawed IMO.
We all know that rucks rarely look like the lawbook pictures, but lets not make them worse by allowing something so negative to become 'standard' practice :nono:
