Brisbane will be without improved defender Jack Payne for Sunday's intriguing twilight encounter against the Adelaide Crows due to concussion.

The 23-year-old suffered a head knock during the Lions QClash victory over Gold Coast, placing him in the league's mandatory 12-day concussion protocols period.

Payne has been having a career-best season, establishing himself as one of the improved intercept markers in the competition.

He has claimed some major scalps this season, nullifying last year's Coleman medallist Charlie Curnow, former No.1 pick Jesse Hogan, and Fremantle youngster Jye Amiss.

In welcome news for the in-form Lions, damaging half-back Daniel Rich will return for the clash against the Crows. Rich has missed the last three matches due to a calf injury sustained against Fremantle in Round 7.

Meanwhile, Keidean Coleman will be closely monitored this week after experiencing glute soreness during the Suns game.

Brisbane's injury list has taken a hit with hard nut Rhys Mathieson (hamstring) out for up to six weeks, forward Shadeau Brain (shoulder) and defender Noah Answerth (concussion), all hurt in the Lions' 117-point demolition of Coburg in the VFL.
