I was very surprised that Isa escaped a charge for his peculiar attempt to tackle Cox by leaping towards him with his knee leading.

The disciplinary outcome was:
"Player jumps on approach into tackle. Knee is promoted forwards however knee does not make contact with opponent".

That doesn't really promote any confidence in the process does it?

I always keep an eye out for Sam Powell too.
He's had 11 cases against him since July 2014 compared to 3 for Farrell in the same period.
All but one against Powell were for dangerous contact in the tackle, yet he has been charged only once.

I've watched the game again and Willie Isa did two assaults on Cox that were to say the least dangerous. I would not in any way call them tackles. Cox got hurt (but tried to brush it off) and was lucky not to suffer more damage. One was picked up by the commentary team saying he led with his knees. The disciplinary committee reported that he did indeed led with his knees but made no contact with the attacking player with them. It's a bit like swinging a big punch and missing ... and so being let off for it. Players with the ball need more protection.
* Sorry about this. I wrote this at the same time as above comment was appearing. I too have always noticed Sam Powell ... he is a dangerous little man who comes in late and low

EGP taken, misses the game at Wakefield on Sunday.

I remember Brent Webb getting binned twice in a game (London away I think) - can't think of any other instance though

iirc thought that was against us at the HJ. One for fighting with Ben W the other for backchating the ref.

Both are correct

Paul March of Wakefield got two yellows by Ganson at Bradford.

I'll have to go undercover to have that pooh, now. Mind you, Michael Fagans managed to get himself into Her Maj's bedroom in the 80's. Hope the Corgis don't catch me. I'll just blame it on them.
