When I went to watch South London Storm lately, their winger connected with a nice slide tackle to prevent one of the West London players scoring. Referee gave him a yellow.

Was the try scored? If not, was a penalty try awarded?

Sometimes the referee isn't in the position to bin a player for a number of reasons. One would be that the game does not warrant a sin bin and another would be that the officials didn't get a clear view of the incident and it would be better to get it checked by someone else.

I'm a Wigan fan and the Sykes tackle should never have been binned. Not seen the Wilkin trip but as someone has said, a trip is an automatic sin bin

isn't the guidance that you can be sent off if the trip is seen as premeditated or dangerous, and not merely a reaction type of trip, ie. sticking the leg out to try and stop a kick through?

Trying to stop a kick is mitigation enough, yes.

However trips don't have to be premeditated - a reaction to being stepped is also a sending off.

No, no.

Coming back the OP post, I also understand that current guidance remains on high tackles that they are either penalty's or a Red Card offence and that therefore yellows should not be given for a specific high tackle?

As such if still current advice, this means that a high tackle is not a sin-binning offence, but if a player commits a number of less serious high/grapple tackles that don't individually warrant a red card he can get a yellow and possibly a red. I seem to remember that Brent Webb got binned at Quins one year for three poor and high tackles in the first half?

I will check but what you are saying sounds right. I have never binned anyone for a solitary high tackle. When a player makes reckless or deliberate dangerous high contact they should be dismissed. Careless high tackles should be addressed with a penalty and a word of advice to the tackler. As you say, we do see people being sent to the sin-bin for high challenges but these tend to be the result of not one but several indiscretions by the same player or team.

As I understand it, the RFL did float the idea around of an automatic yellow for grapple tackles earlier in the season, but this initiative seems to have now stopped.

IIRC it must still have been in place when Wigan visited Headingley earlier in the season, hence Jeff Lima's yellow for what was considered to be a "cannonball" tackle on Chris Clarkson?

That yellow was for dangerous contact. A comparable offence would be the chicken-wing.

goes to show how much you know mate!!! in 2003 stanley gene was red carded for tripping in the buddies cup final, tripping in the field of play is a red card, the reason wilkin didn't recive one was ganson never saw the incerdent and had only the touchjudges word for it, hence a one match ban was given.

Oh I remember the sin bin. That's the board where people argue in favour of pedophiles getting huge handouts because their case was put back a few days and they were caused distress.

Oh the other kind...now that is a distant memory. Referees don't pull out a yellow so much any more. Instead they do this bizarre cross armed hand gesture to signify they're going to chicken out of making a decision themselves so it can be successfully politicised by people behind closed doors instead.
