Ronaldo was capable of returning to the field against the Cows, I'd say his problem is ongoing and they are managing it while we are short. Dugan needs to pass HIA protocols, anyone know what that actually entails? NRL.com has Katoa back Rnd 8-10.
There's a 6 stage return tor sport program they need to follow.
Starts with 24hrs rest
Then limited activity (24hrs)
Light Aerobic exercise (24hrs)
Sport specific exercise (24hrs)
Non contact training (24hrs)
Full contact training after medical clearance
*Under 18s need to go twice as long between, ie 48hrs so that's why juniors often miss games after a HIA.
Return to play/games.
If the player experience any symptoms as they progress they go back a stage and go again. That's why if there's a 6 day turn around between games the players miss a game as there's not enough time, additionally if they even go back one stage they're often at odds to play.
So if Dugan had failed any of the stages so far he'd have been ruled out as there wouldn't be enough time to get through them all. He's probably on Sport specific exercise now.
