Carlton and Collingwood joined forces for a good cause this morning with the 13th annual Peter Mac Breakfast.

Coaches and captains from both teams came together in the Member's Dining Room at the MCG to help raise vital funds for cancer research.

The Peter MacCallum Cancer Centre is Australia’s only public hospital solely dedicated to cancer and the home of Australia’s largest cancer research group.

Peter Mac treats more cancer patients each year than any other hospital in Australia.

Since its inception the Peter Mac Breakfast has raised more than $1 million for the Peter MacCallum Cancer Foundation.

When the Blues take on the Pies at the MCG on Saturday they will be playing for the Peter Mac Cup – Australia's longest running charity match which is now in its 23rd year.
