"And I forgot Freddy [NSW coach Brad Fittler] came in to check on me. I was a bit spacey. Loading "I'm fine now. It was more how I felt [on Sunday] night with the headaches and all that." The NRL has written to both the NSWRL and Queensland Rugby League to explain the use of the brain bunker, a remote facility used to monitor potential head knocks in real time. It can then relay information to on-field medical staff and doctors, which can be used to evaluate a player's suitability to stay in the game.

The use of independent concussion spotters stationed in the crowd, which has been in use for previous Origin series, will be scrapped. Each team will have two gameday doctors as per NRL rules. "The states have been given written instructions about how the bunker will work," NRL head of football Graham Annesley said. It’s cutting edge in world sport to have these sorts of things monitored live so doctors can be instructed to review incidents Graham Annesley "It’s absolutely and completely thorough. It’s cutting edge in world sport to have these sorts of things monitored live so doctors can be instructed to review incidents. "It’s taken a while to get it to this point, but we introduced it at the start of the year so we don’t need people live at the venue other than the people in the tent. If there needs to be any conversation between the doctor when he comes to look at the video and the spotters in the bunker that can happen as well on a particular aspect of play."

Fittler entered the dressing-room at half-time on Sunday to check on Frizell. After realising Luke Keary was in a bad way on Friday night, Fittler said Frizell was not much better on Sunday. "Obviously watching the game I was nervous for him and worried," Fittler said. "When I spoke to him, I don't think he knew who I was. He had that stupid smile going and talking about seeing the doc to go back on. "Given the year he has had with the severed teste, the [poked] eye and now the concussion, there will be protocols we follow and the actual rest for him will be great. "He'll be allowed to do stuff by Friday."

Frizell admitted he was not in the greatest form coming into an Origin campaign and had not been helped by the run of injuries. The lacerated testicle he suffered in a freak accident happened in week one, then the poke in the eye occurred against Parramatta earlier this month, forcing him from the field because of poor vision.

"It hasn't been the ideal start for myself and I haven't been in this position before with so many different injuries happening so frequently,'' Frizell said.
