Wally Lewis says he's losing the strengths that made him 'The King' as he continues to live with the brain injury he developed while playing rugby league

The Queensland league great used an address at Australia's National Press Club address to call for an 18 million dollar investment towards support services and education about CTE.

After a string of head knocks throughout his legendary playing career, Lewis revealed last year he'd been diagnosed with the condition and wants more awareness about what living with it is like.

Lewis believes tackling technique particularly at the elite level must continue to be drilled into players.
