The legendary commentator, 73, was diagnosed in May last year with myeloma – which has the lowest survival rate of all blood cancers.
Doctors shocked Roberts with his diagnosis after the long-time footy caller fell and broke his ribs, with the x-rays showing up a unusual result.

Before his retirement in 2019, Roberts called more than 1100 AFL games and gave voice to multiple Summer and Winter Olympics, Australian Opens and Melbourne Cup carnivals.
