Brisbane defender Darcy Gardiner's future in the Sunshine State remains uncertain as the 26-year-old will not be making a decision until after the club's finals campaign.

According to the AFL's Cal Twomey, the Lions have offered Gardiner a long-term contract which they are confident the stopper will take, but for now, he remains determined on the task at hand which is helping his club reach a Grand Final.

Many Victorian clubs have been monitoring Gardiner's situation as they search for his signature, but as an unrestricted free agent, any club would have to match Brisbane's multi-year deal to lure him away from the club.

The 26-year-old has had a consistent year for the club, playing 20 out of a possible 24 games and proving his worth in big matches for the club, especially in the current finals series.

Gardiner will also be finishing up his ninth season at the club this year, amassing a total of 153 games for the Lions over that time.

In other news, Brisbane key-position player Dan McStay looks set to leave the club for Collingwood, exercising his free agency position, whilst club leaders Mitch Robinson and Dayne Zorko remain uncontracted for 2023.

Young stars Tom Fullarton, Jaxon Prior and Deven Robertson are also among those that are uncontracted at Brisbane beyond 2022.

A decision on Gardiner's future will be made within the next fortnight, with Brisbane's campaign either ending on Friday night with a preliminary final defeat or following the final Saturday in September.

Since joining the Lions' pride with the 22nd selection of the 2013 National Draft, Gardiner has donned a maroon, blue and gold guernsey on 153 occasions.
