On the weekend, the Newcastle Knights received an email from Michael. Here is what he had to say.

'Hi team,

A few weeks back we reached out to Kalyn Ponga to arrange to get a signed jersey for our nine-year-old's birthday.

We just wanted to say a massive 'THANK YOU' to the Knights and to KP for making this happen!

As you can tell by the video, this truly made our sons birthday special and one he will remember forever.

Thank you Knights and KP!'
