FREMANTLE has handed Harley Bennell and Hayden Ballantyne contract extensions, with the duo to stay on at the Dockers in 2019.

Bennell has been consistently struck down by a string of calf injuries this season, although he is reportedly close to senior selection after overcoming numerous setbacks.

The talented former Gold Coast midfielder has been hampered by injury in his three seasons at Fremantle, managing just two senior matches in 2017.

"I'm very excited, we've got a young bunch of boys coming through and I can't wait to play with them in the coming season," Bennell told the club's website.

"Coming back, I've played 10 games in the WAFL for [WAFL affiliate] Peel (Thunder) which has really helped me.

"As the season went on, I felt I got better each game."

Bennell praised coach Ross Lyon for his support through a challenging year.

"Ross has been really good. He's been like a father figure for me since the day I got here," Bennell said. 

"His support as well as (football manager) Chris Bond and (CEO) Steve Rosich have been outstanding. I'm just looking forward to working with them for the year ahead."

Rosich lauded Bennell for the resilience he has shown.

"It's pleasing that we are in a position to be able to offer Harley another contract," Rosich said.

"Despite going through some tough periods with injury, Harley has continually kept his head up and worked extremely hard at getting back on the football field.

"We've seen Harley play 10 games in the WAFL this season and we have every hope he can return and play his best football in a Fremantle jumper."

Ballantyne has been in and out of the Dockers' line-up this season, but has still kicked 17 goals in 15 matches.

"I'm stoked to be around the club for another year," Ballantyne said.

"Obviously, it's probably coming towards the end of my career. It's another year in the purple and I’m very proud to play at this club for such a long time.

"I look forward to some more good times ahead."

More to come.
