Quote: The Reaper "Yeah I get that, the problem with this current ruling is it actually encourages players to stay down if they've been hit high, because it will get reviewed and if they're right then they won't have to take a green card or a sub.
It definitely is a tough one to solve, there are pros and cons to all of the suggestions but obviously welfare does have to come above all. Thats why I think the best bet is to let the VR review the incident as play goes on, and then can advise the ref who can dish out any sanctions at the next stoppage in play. Of course this isn't ideal as you can be missing out on a pen but at least it stops the thought of "oh I'll stay down here and he might get a yellow/red" as if warranted then it'll happen regardless.'"
Whilst I agree in principal in what you say it would be really difficult to police effectively as some reviews may take longer than others and there could have been several PTB's before the VR has had a proper look and a try may have been scored in the mean time, so where do you bring it back to, what if the non offending team intercepts a pass and goes the length of the field and scores, do you deny them a try to bring it back 70m for a penalty, the restart would potentially be a nightmare for refs to decide upon.
Like you say player welfare has to trump everything else, especially with the law suit cases going on at the moment, but there is no one fit for it.
