Robbie Tarrant is eyeing a switch of position, as he takes another step forward from leg surgery.

The 25-year-old, who was restricted to just one AFL game last year due to a stress fracture in his tibia, completed game sense training drills on Thursday for the first time since the operation in June.

Tarrant said making the move from attack to defence remains a work in progress, but he’s aware of the challenges that come with a new position.

“I’m learning the role now and I’ll jump in with Scotty Thompson, ‘Narni’ (Nathan Grima) and Lachie (Hansen), and try and learn some things off them,” Tarrant told NMFC.com.au on Thursday.

“I’ll probably look to play on the bigger sort of forwards; I still back my running in against most (players).

“I know the forward role relatively well now so I can always flick back forward, but I’m going to give it my best and hopefully I pick the defensive side up pretty quickly and that works out.”

In a further boost, the 196cm big man hasn’t pulled up sore from training for the last “three or four months” and said building continuity on the track is another short term goal.

“It’s probably the most sessions I’ve done in a row for a good four or five years,” he said.

“Although I haven’t done the game sense (until today), I’ve been able to run since mid-September.”

Tarrant is aiming to put his horror run of injuries behind him and add to his 39-game tally as he embarks on his eighth year at Arden Street.

The number 25 said the support, particularly from forwards coach Shane Watson and defensive coach Josh Drummond, had kept his confidence levels up after a "nightmare" 12 months.

“They’ve both been really supportive and it’s encouraging to (hear them) say that you can still play,” he said.

“I haven’t just been injured for the last year, it’s been a seven or eight-year period where I’ve struggled to go through the whole year without getting injured.”

While achieving his 50-game milestone is another objective, Tarrant is eager to add to the Roos’ recent on-field success.

“Fifty games is still the target, (but) it is what it is and I can’t control that,” he said.

“I’d love to get to as many games as I can individually, but the most important thing now is I think we’re in a good window for some team success and I just want to be a part of that.”
