There was only one trainer with Dion straight after the hit, then another trainer went and helped. I think they were trying to get more assistance from the Richmond bench in calling for the Doctor, more worried about his condition than a stretcher at that time. One of the umpires (3 on the *smile* ground) should of seen the drama and went over asked the question "is the player ok"? But didn't, then play was going on around him and still no stop in play, umpires a lot more at fault than the RFC medical staff.
One thing about this whole incident, Dion Prestia is one tough prick the way he walked down to the rooms by himself for the concussion test after that hit.
Yeah agree Jake. The umps had the primary duty of care.
