St Kilda defender Dylan Roberton will miss the remainder of the 2018 season to allow doctors to work out the heart scare he had earlier in the season.

Roberton collapsed against Geelong and was taken to hospital for testing immediately.

He may return to the club to help coach the club’s backline.

Roberton talked about what happened during the incident.

“I just remember watching the ball go up and getting dizzy but that’s about it,” he said.

“It was a bit of a scare, probably more so for family and friends. I was fine straight away."

Roberton reported “dizziness and a blackout” after the incident but was able to walk from the field.
