THE AFL has reinforced its commitment to the Recognise campaign in support of the constitutional recognition of Aboriginal and Torres Strait Islander people in Australia's founding document.

"The AFL has benefited from great indigenous leaders and players, who have helped make our game what it is today," McLachlan said.

"The Recognise campaign will be a feature of every AFL game and fans will see the big 'R' for Recognise at the grounds and on the cover of their AFL Record."

Nine clubs have joined the movement towards constitutional recognition and will feature the R on their indigenous-themed guernseys.

Tanya Hosch, joint campaign director for Recognise, acknowledged the strong and growing support of the Recognise campaign by the AFL, many of its clubs and players.

"Twenty years ago the AFL took a stand and said there's no place for race discrimination in footy. Now the Recognise movement seeks to ensure there's no place for race discrimination in the Constitution either – and to fix the historical exclusion of the first Australians, Aboriginal and Torres Strait Islander people," she said.

Sydney Swans great Adam Goodes, Hawthorn superstar Shaun Burgoyne and Essendon champion Jobe Watson are just some of the big names who have thrown their support behind the initiative.
