Essendon midfielder Dyson Heppell has undergone a successful operation on his left knee earlier this afternoon.

The 22-year-old had complained of some discomfort during yesterday’s main training session, and scans revealed he required surgery. 

Club Doctor Bruce Reid said Heppell remains on track for the season opener against Sydney.

“Dyson’s surgery was successful, Julian Feller removed a flap of surface cartilage from his left knee,” Reid said.

“The process moving forward is to let Dyson’s knee settle over the next two weeks.”

“We will continue to monitor Dyson during this period and all going well he will be able to commence training in a fortnight.”
