INJURY-CURSED Fremantle star Harley Bennell has taken a significant step toward his much-anticipated return, training with the Dockers' full squad for the first time this season at an open training session

Bennell could be as little as 2-3 weeks from his comeback after suffering repeated calf trouble since his last appearance for Peel Thunder in March last year.

He last played at senior AFL level in round 22, 2015 for Gold Coast against Port Adelaide.

The 24-year-old appeared in good spirits and moved freely on the training track on Wednesday.

He joined in the full warm-up, strode out at pace during run-throughs and completed skills work with his teammates before the session was closed to media. 

The former Gold Coast midfielder has been earmarked by coach Ross Lyon for an explosive role in attack – a la Hawthorn star Cyril Rioli – with bursts in midfield when he finally makes his Dockers debut. 

Bennell booted 92 goals from 81 games for the Suns before he was traded to Fremantle at the end of 2015, and could add some X-factor to the Dockers' youthful forward line.

But he will return via the WAFL before he is considered for AFL selection.

Bennell has undergone a painstaking rehabilitation marred by setbacks and some controversial off-field incidents.

In April, he was asked to disembark a flight to the Gold Coast for being intoxicated while he was on club leave in the wake of his latest two-month calf setback.

Bennell was then fined $10,000 – half suspended – and ordered to undergo counselling to deal with his personal issues following a club investigation into his bizarre behaviour at a Peel match in May.
