Fremantle’s Harley Bennell has suffered yet another calf injury, casting serious doubt on his ability to make it back into the AFL.

Bennell suffered the latest injury training at Cockburn this morning. He was already on a modified running program due to a minor calf strain last week.

The 26-year-old stopped mid-lap and sat near one of the light towers at Fremantle’s training venue for a considerable period of time before walking from the field.

General manager of football Peter Bell said the club’s medical staff would await the results of a scan.

“Harley sustained an injury to his left calf this morning while training away from the main playing group on a modified program,” Bell said.

“Our medical staff will await the results of a scan, which will establish the extent of the injury, the treatment required and a recovery plan.”
