Jed Adcock has been told he is not guaranteed a spot in the Senior side for the 2016 season, as the Club opts to fast-track the development of its young talent.
Adcock, who played his 200th game for the Club against North Melbourne at the Gabba in Round 17, met with Senior Coach Justin Leppitsch earlier this week.
Brisbane Lions CEO Greg Swann said Adcock wanted to know his future before the end of the Season, and Leppitsch had been up-front with him.
"He came to Leppa (Leppitsch) and said he wanted to know what was happening next year," said Swann.
"Leppa told him we're going down the youth path and his spot wasn't guaranteed.
"We wanted to be fair and honest with him, he deserves that because he has been great for this Club over the years
"It was not an easy conversation to have because Jed has been such a fantastic servant.
"But we believe the best way for the Club to go is to really develop the talented youngsters we have, as well as adding more young talent to our list."
Adcock has played 203 games for the club and was co-captain and captain from 2013-2014.
