Roberton collapsed in a game earlier this season and has been ruled out for the rest of the season.
It was later revealed that the 27-year-old had issues with his heart which caused the collapse.
In good news, Roberton returned to training with the team earlier this week; Participating in light running.
Frawley, St Kilda’s part time defensive coach spoke on how everybody at the club felt when Roberton made his return to the training track.
“The players were up the other end of the ground to me and they were all yelling and I was wondering what was going on,” he told SEN Breakfast.
“Dylan Roberton was running a lap with Jarryn Geary and all the players got around him.
“It was great to see, this kid is probably number one, two or three in St Kilda’s best player and he’s got three young children.
“He’s had a really significant illness with his heart and touch-wood, he had really good news from the doctors on Monday, he’s able to join in some training, nothing over the top, but initially he wasn’t allowed to get his heart rate over 80 or 90 so I think that’s great news for Dylan.”
