Personally, I reckon it is game over.
My logic is that the restart after a safety stoppage would be a scrum; and as time has already expired, the game comes to an end when there is either
- a Lineout
- a Drop Out
- a Scrum
- an option
- a FK or PK.
If it was a genuine injury, it is game over.
Them's the breaks.
If wasn't genuine ?
Or what if a physio came on, genuinely concerned, not as a ruse, and then realised she had made a mistake and wasn't needed (there was a football game wasn't there with something like that )
I think it's a tough one
If it was genuine then fine. Sorry, I thought that was obvious.
You are there to make the call. It may well be a tough call. But that is why we get paid such big bucks (not).
If it is genuine then there is no offence. you have NO law justification for continuing the game.
If it is NOT genuine (in YOUR opinion) then a player going down feigning injury is a PK offence so the game is not over!
A pitch "invasion" that causes the game to stop is extenuating circumstances and should be treated as such. also, remember, a "medic" coming on to treat a player does not mean the game must stop.
