Triple M presenter and former Crow Andrew Jarman will take an icy plunge for a good cause, as part of Adelaide’s Round 13 clash with Richmond.

Jarman has been unveiled as the second personality to be dunked with icy water at the SA Freeze event at Adelaide Oval next Thursday night.

Jarman said he was keen to be involved in the event, which aims to raise much needed funds and awareness for motor neurone disease.

“I’m feeling emotional and excited to be a part of this great event,” Jarman said.

“Now I’ve just got to sort my outfit out, but I’ll come up with something.

“To see so many families and individuals suffering with this insidious disease is just horrible.

“We are only playing a small part in helping to fight MND, but it’s so important for us to do what we can.”

Other celebrity dunkers will be announced in the coming days.
