I suppose it's just me who thought it looked pretty suss yesterday.
The knock didn't look like much, but despite everyone telling him to not lay around after a headknock after what happened last week, he went straight to ground and had a little sleep, till he jumped up and looked just fine for the rest of the day.
Meanwhile, Brailey got up as quick as he could and tried to look unaffected, but was staggering around like he had 15 schooners in warm up.
Ponga got level 1 and Brailey got level 2. I'd have called it the other way around. I didn't see any sign of Ponga being concussed other than him lowering himself to the ground and playing dead, while Brailey was clearly staggering for minutes.
