Yeah, this is the worst aspect in a nutshell. Catalans will ultimately weaken player protections if they carry on with this. The other coaches need to pressurize MacNamara over the issue too.

One of the "concussed" Catalan players even sprinted off the pitch!

2 easy ways to counter it:
Independant concussion doctor makes the call
The free sub is when you lose the player to concussion.

Example of the current rule being wrong is Cas lost McMeeken AND a sub early in the game due to concussion, Catalan got 2 free subs by faking needing a concussion test. So in essence they had 3 extra interchanges and an extra man on the bench.

Correct,and next time anyone tries it, they should be penalised for moving off the mark.

A good answer to solve this has already been given. If the player comes back on after a head test, then it
should be counted as an interchange. That'll stop the fakers.

This is one of my real bug bears & is embarrassing when referees fall for it. It seems that the quest for a speedy game has led to referees refusing to enforce certain rules against the attacking team.

Stand by for 3 Catalans players taking head knocks with 10 mins to go...and all miraculously passing the 6 day assessment just in time for next week's game...

Ha ha nice one, I never thought of that.

There were loads of these instances at the start of last season and following a bit of "outrage" from various quarters, it stopped.
Huddersfield were "fine exponents" of playing the ball (and passing/ throwing it) into an offside player, usually passing/ throwing the ball downwards, clearly not towards another player.
Sometimes this is fair enough but, they (and others) were taking the P., again, this stopped after a couple of rounds.

Likewise Wigan lost Clubb 2 minutes after he was subbed on, so essentially lost 2 subs and the man from this.

Junior Sa’u went off holding his ribs Friday night v giants and then went for a head test

Pinched off Nottinghamtiger :

On two occasions Catalans had a player stripped off and ready to replace a concussed player before he became mysteriously “concussed”, having a 15 minute rest and returning to the game just before the interchange would be converted.

They're on tv next game right? I think for the first game they get the benefit of the doubt, but if it happens again against Huddersfield then yeah, time to do something about it.
