Cancer survivor Adam Ramanauskas has urged Hawthorn fans to temper their expectations of an early-season return for Jarryd Roughead.
"What can happen, if he pushes it too hard, too early, that can be a major setback for weeks at a time, not just a day or two," Ramanauskas told RSN radio.
"I think he's out there, he's enjoying training and he's seeing how it goes.
"There's a lot of issues around getting your heart-rate too elevated in the early stages of his recovery. He'll need to be very, very mindful of that."
