Marion thanked everyone who have supported him in his journey to the Tokyo Olympics.
"Thank you to family, friends, partners, and the whole of Samoa for your support for our son Tino. Unfortunately Tino got eliminated last night by points after his preliminary fight against the Zambian champion," he posted on Facebook.
Marion will return to Australia when he resides with his family after the Tokyo Olympics is done.
