Tooheys news from other thread (thanks Billy) mentions Ponga playing with rib cartilage issue - playing through pain.
Often referred to as a very painful injury.
Usually the biggest issue is the pain as far as I’m aware - which would be limiting movement and I assume not very pleasant to be tackled with.
Not sure how effectively it can be needled.
Most things I’ve looked at in my comprehensive search (2 minutes googling NRL physio) mention most players seem to get on top of it in 2-4 weeks. With most succumbing to it after playing through pain for a few weeks.
Interesting to see if we hear anything official, and how he approaches his origin availability.
