Seriously poor reffing. I don't care if people think it is salt. That was a double movement every day of the week except for Panther's games. He tucks his arm into his chest then spreads his arms out after he bounces and it ends up at shoulder height. A movement. He could have left it tucked and maybe scored, but he moved the ball forward. Penalty.
The head clash happens. I see that as bad luck but probably nefarious from Penrith, BUT to have physically a lasting effect on the player due to a head injury on a play that was penalised, THAT should allow for 18th man to come in. Also, they should be allowed to have HIA assessments repeated when a player can't return. Even concussions can take a while to set in after adrenaline is pumping.
The multiple infringements on the line by Penrith including a 6-again just before the Broncos run it into touch (total 4 infringements in a row) clearly shows intent and should be punished. Send a bloke. No excuses here.
I could go on, but I have pizza to eat
