Along with his dad and club coach Paul, and other volunteers, he has helped organised another All That Malarkey event.
It returns to The Carlton Club on Friday 12 June, with all proceeds this time going to Holly's Hearts.
The charity helps children like Mack, who have cancer, to enjoy experiences that create special memories.
The last event raised more than £11,000 for Young Lives vs Cancer.
Acts this time include:
- Comic Smug Roberts
- Poet Kieren King
- Musician Daniel Darley
Mack's story:
"When I was nine, my mum and dad told me I had a type of cancer called leukaemia.
"I didn't know what it was because I only went to hospital with a rash.
"The medicine made me really poorly and I was in intensive care. I then spent over 100 days in a row in hospital, which was a long time.
"I still have it now, but I am home and am now able to travel to hospital for chemotherapy, rather than stay there.
"It makes me feel sick and rubbish and I miss playing football.
"Me and my dad had the idea of doing something for charity to help other families like mine.
"So dad and his friends have organised events and I have loved helping out. It has given me a good thing to do."
