Allen Christensen says though he's nervous about returning to the AFL, he's hopeful he can soon rediscover his form for Brisbane.
Christensen has been on the sidelines since round 11 of 2016 when he fractured his collarbone.
He's suffered the same injury twice in the past 18 months as well as enduring a crack to the plate used to strengthen the area.
Now he's fully recovered, and is launching into pre-season with the Lions.
"I'm a bit nervous," he admitted. "The game has changed since midway through last year so much - we play a different game to when 'Leppa' (ex-coach Justin Leppitsch) was here.

"Like some of the players, I'm still getting used to some of the structures because I haven't been able to implement them in games, yet. Hopefully it's like riding a bike."
The former Geelong premiership player missed the whole of coach Chris Fagan's first season in charge, but says he's been excited watching the development of the young players who have been under his guidance as a leadership group member.
As far as his shoulder goes, he won't be protecting it when he returns to action.
"I've taken the approach that if it happens again, it happens again," he said. "I'm going to put myself into situations where it could break again - it could break for anyone. I think it's a pretty important mindset to have."
Christensen, who won a premiership with the Cats in his first season in 2011, has played 98 games in his seven seasons in the AFL.
Brisbane are 5000/1 to win the 2018 Grand Final.
The Lions are 500/1 to finish in the top eight.
