I did not go to the game but just watched the highlights here rlhttp://www.skysports.com/watch/video/sports/rugby-league/10181672/wigan-20-16-salfordrl

I am gob smacked that knock on was not spotted!

No need to move the hand in to the ptb just leaving it there is a penalty.
If it had gone to the VR at best a penalty to Wigan and worst play on and the try awarded.

Well it looks like Mr Stokes performance has been rewarded this week with a nice weekend off.
Very well deserved

The Salford players did say things,also the post match interview by the coach had a mention of it being a knock on,all the press thought it was a knock on.Coincidence that the ref isn't reffing this week ?

Read Stuart Cummings article in Mondays League Weekly, he explains exactly what happened with the ptb. The referee was wrong on two counts in that incident.

In fairness both sets of fans agree that he had a shocker and so deserves to be dropped this week.

From looking at the reply, our guy was interfering with the ball so it should have been a pen to Wigan. They kick the goal and win
