Im not going to compare the two incidents because im not sure they are comparable or what the point would be, But i would say that a concussion is not a little injury, its not a simple headache. Its other name is Traumatic Brain Injury.

I would have give him 10 because it was a swinging arm, but it did bounce of the ball so red was very harsh imo, maybe all the refs are on edge after Ferres and Westwood incidents

Thaler IMO got it just as wrong as Child did the previous week.

What the game needs is neither an under or over reaction - it needs to get these decisions correct.

My first reaction was 'that's a really bad one red card', it looked awful and reckless full speed so can't blame the ref,Only on the slow mo replay did you see different. I believe the video ref should be used. That would have taken less than one minute to sort out. Obviously, at a non televised game this would not be possible and that would still have been red today were that the case but i'm a firm believer in if you have the technology then use it.

Spot on Biff.
Unfortunately for Saints and what has gone on previously Amor got a red when ten minutes would have been the right call.

After what happened last week I expected there might be one somewhere this week and I'm not surprised it involved Thaler - always had a trigger finger IMO. The referee wasn't in a great position to begin with starting with his back to the incident looking over his shoulder while retreating, possibly missed the initial impact on the ball but seeing the (indirect) contact with the head. It looked like Tommy Lee got more of Liam Harrison than Kyle Amor did.

Expect St Helens to fight this one but still lose as the judiciary back it's official.
