Brisbane defender Marcus Adams has been moved to the inactive list as he continues to suffer from a concussion sustained late into last season.

Adams suffered the head knock in his side's Round 21 clash with Carlton at the Gabba last year, with delayed concussion symptoms ruling the backman out of the remaining rounds of the season, along with the Lions' finals push.

Having continued to battle with the symptoms, the Lions have moved Adams to their long-term injury list, likely meaning the 29-year-old won't play for the entire upcoming season.

“Unfortunately, Marcus is dealing with a serious injury that will unlikely see him play in 2023,” Lions football boss Danny Daly said in a club statement,

“While he is making some progress in his recovery from concussion, he continues to experience symptoms and his health and wellbeing remains the top priority.

“The Club is fully supportive of Marcus and his recovery, and he will remain involved with our footy program.”

The list call means Brisbane are able to add to their list through the Supplemental Selection Period, which expires on February 15.

Brisbane have already signed former Bomber Conor McKenna through the SSP window and will again assess their options on the open market.

The Lions have invited delisted St Kilda defender Darragh Joyce a chance to train in Springfield ahead of the new season.

Joyce was cut from the Saints after 13 games in six seasons at Moorabbin, having first joined the club as a Category B Rookie from Ireland.

Standing at 194cm, Joyce is a like-for-like replacement for Adams, who has been a steady talent on Brisbane's last line since switching from the Bulldogs at the end of 2018.

Since leaving St Kilda, Joyce has linked up with Collingwood's VFL squad for the season ahead.

The Lions can hold off on filling the new list vacancy in favour of using their open list spot at the Mid-Season Draft.

Adams' absence is set to open opportunities for the likes of Jack Payne, Carter Michael and Darcy Wilmot in Chris Fagan's side to start this season.

Brisbane open their 2023 campaign against Port Adelaide in South Australia on Saturday, March 18.
