This one is different because it was clearly a Cat 1 injury. Cat 1 is when a player shows signs of 'motor incoordination' or to put it simply the player stumbles and staggers when getting up, with cat 1 injuries the players don't even come back if they pass the HIA. If you remember origin game 1 last year Cordner for hurt went off, passed his HIA and came back on but afterwards NSW were hit with a formal caution as the NRL said Cordner's injury should have been assessed as a Cat 1. Lewis was a textbook Cat 1 and we left him out there, no HIA assessment for another few plays, really the trainer should be sacked for negligence
