Curran's three years at Arden Street were ravaged by recurring right navicular stress fractures, with the key forward undergoing three operations in little more than a year.
But after making little significant progress in his rehabilitation from his most recent surgery, Curran accepted medical advice midway through the 2014 season that he give his foot a year's rest from all forms of running.
"There's a lot of cartilage damage in the foot and it will take a big sort of effort for it to heal," Curran said.
"I'm a realist and know (returning to the AFL) is a very slim chance, but it's not one that I'm going to give up on."
