ALL 18 coaches will head down the slide and plunge into icy water ahead of the Queen's Birthday clash between Melbourne and Collingwood for the Fight MND's Big Freeze 4 campaign.

Led by former Melbourne coach and Essendon player Neale Daniher, who has been battling motor neurone disease since 2013, all coaches will immerse themselves in a pool of freezing water to raise money for the illness that has no known cure.

Daniher nominated Richmond premiership coach Damien Hardwick as the first slider and the other clubs' head honchos quickly followed suit. 

This will all happen at 2pm AEST on Monday, June 11 at the MCG. 

Gates open at 1.30pm AEST.

At least two Australians die each day as a result of MND.
