Staphylococcus aureus isn't that deadly - only if it enters the body, so hopefully this can be contained. I know that heart murmurs and open-heart surgery are pretty routine these days, so hopefully nothing goes wrong there.
I really don't care about his playing career at this stage, but I really care about his welfare and well-being and hope he can make a full recovery. Everything else including his playing career is not a priority at this stage.
All the best Tuipulotu, we're rooting for you.
