BACK in action following their byes, Brisbane and Sydney meet in a Thursday night blockbuster at the Gabba.
Brisbane (8-6) got its campaign back on track with convincing wins against the Suns and Tigers before heading into a bye and can now return with eyes fixed on climbing into the top six.
LIONS v SWANS Follow it LIVE
The Lions will get a better idea of their standing with back-to-back games against premiership fancies in the Swans and Cats, but there's little margin for error if the reigning premiers are to avoid the wildcard places.
Sydney (12-2) returns from a bye and a chance to reset after it pulled off a pair of nail-biting victories against sides sitting outside the top 10 even while it was below its best.
The Swans are well-placed for a top-two finish that would earn an early home final, although they now begin a tough run with games against the Lions, Bulldogs, Dockers, Crows and arch-rivals the Giants that could shape their position.

Meanwhile, the Lions welcome back defender Ryan Lester in place of youngster Shadeau Brain.
