“I just want to thank my friends and family, not just my family, but all families – especially the Queenslanders who have been gone six to eight weeks now.
“We appreciate the efforts to keep the championship going. Thanks to the fan base, everyone who came out, everyone who was watching at home.
“I would especially like to thank my colleagues. We were thrown into the arena, walked hard, fought each other. I wish everyone a safe, happy journey and good luck. “
