“Chris has found it difficult to meet the demands of AFL football given his personal issues,” Richmond general manager of football, Neil Balme said.

“Ultimately it was agreed with Chris, and his management, that stepping away from the game is in the best interest of his long-term health and wellbeing.”

Yarran said he greatly appreciated the support of Richmond over the past 12 months.

“I am extremely grateful for the support Richmond has given me over the past year. I am deeply disappointed my ongoing health issues have not allowed me to repay the Club and its supporters,” Yarran said.
