Brisbane ruckman Stefan Martin is yet to be handed a contract fro 2021, with the Lions veteran facing an uncertain future in the AFL.

Martin, who turns 34 next month, has been out-of-favour in Chris Fagan's side in 2020, playing just eight games in 2020

The veteran ruckman joined Brisbane from Melbourne at the end of the 2012 season, with Nine now reporting Martin's future isn't as clear as first hoped.

Martin featured in Brisbane's preliminary final loss to Geelong on Saturday, sharing the ruck duties with first-string tall Oscar McInerney.

The development of Tom Fullarton and Archie Smith may also have the Lions' priorities separated from Martin's plans for next year, while the AFL and AFLPA list and cap size agreement is yet to be finalised.
