Sydney Swans young gun Tom McCartin will resume training after being given the all-clear following precautionary scans.

McCartin received a knock at training three weeks ago and suffered symptoms that required further investigation.

An MRI revealed a concern about possible damage to an artery in the 19-year-old’s neck.

However, further investigation by specialists revealed that the abnormality is something McCartin was born with and will have no impact on his playing prospects.

Sydney Swans coach John Longmire said it’s terrific news.

“Clearly we were very concerned for Tom and it was a difficult few days for his family while we were waiting for medical advice, so we are all feeling relieved,” Longmire said.

“After thorough investigation, our medical team and specialists have found this is something Tom has had all his life, so he’s at no greater risk of injury than any other player.

“MRI scans can be very sensitive and sometimes pick up things that are innocent and innocuous. That was the case here.

“Tom will resume full training on Monday and we look forward to seeing him playing in the coming weeks.”
