"I want to sincerely thank everyone at the Rabbitohs for the personal support they have shown me and my family throughout this process.

"Teammates, staff and everybody behind the scenes have made an incredibly hard situation easier to face.

"To my teammates, thankyou for treating me the same every single day. Within moments of walking through the doors, most of you are making me laugh with the usual banter and I wouldn't want it any other way.

"To my family and close mates, thankyou for standing beside me through all of this. I know the road ahead won't be easy, but anyone who knows me knows I'm competitive, stubborn and ready to fight this with everything I've got. What I need right now isn't sympathy or sadness, what I need is support, privacy and understanding while my family and I navigate this difficult time.

"This is only part of my story and when the time is right, I'll share now, but for now, I ask for everyone to respect my privacy while I work with my doctors.

"Love you all.

"Jai."
