Demons recruit Harley Bennell has suffered yet another calf setback, according to SEN.

The report states that the 27-year old had scans confirming a minor strain sustained after training last weekend.

“Harley pulled up sore following a training session on the weekend and scans have shown a low-grade strain in his calf,” Melbourne football manager Josh Mahoney said.

“While disappointing to have this occur again, we deliberately set expectations on Harley conservatively, allowing for some setbacks.”

Bennell signed with the Demons under the supplemental selection period during the off-season.

Mahoney added: “He (Bennell) understands the importance of undergoing a slow, modified program, and he knows there may be further challenges to tackle along the way,” Mahoney said at the time.

“We think that by making this decision early, it will take away an undue pressure and enable Harley to concentrate fully on this program.

In other injury news for Melbourne, defender Christian Salem is racing the clock to be fit for round one as he battles Glandular Fever.

“Christian has a mild case of Glandular Fever. Pleasingly, he has been improving each day and completing running sessions and it still likely to be in the mix for Round 1,” Mahoney said.
