Former Melbourne captain Garry Lyon has called on Prime Minister Anthony Albanese to write a "dirty big cheque" for FightMND in honour of Neale Daniher.
And Lyon wants the PM to head down the slide into a pool of iced water at what looms as the most significant Big Freeze event of all in a tribute to Daniher.
The former AFL player and coach died of motor neurone disease (MND) - which he campaigned against for 13 years - on Monday, aged 65.
A huge crowd is expected for the Big Freeze 12, which raises funds for research into MND, at the MCG before the Demons play Collingwood in their traditional King's Birthday blockbuster on June 8.
"It's incumbent upon all of us to make sure we're there and that we continue this fight in the manner that he (Daniher) fought," Lyon said on Fox Footy on Monday night.
