What it means for Port Adelaide: This is a chance for the Power (seventh, 8-7) to show their Showdown smashing of Adelaide wasn't a fluke and prove they can be a serious premiership threat.
What it means for Brisbane: The Lions can consolidate a spot in the top four by winning back-to-back matches on the road after last weekend's impressive victory against Greater Western Sydney.
The stat: Lions midfielder Lachie Neale has found plenty of the ball against the Power. Neale averages 37.2 disposals per game in his past five matches stretching back to 2016. He had 43 touches and eight clearances in their 17-point win in round three.
The match-up: Charlie Dixon v Harris Andrews
Andrews is now the No.1 key defender in the competition having overtaken West Coast's Jeremy McGovern, and is 27th overall in the Official AFL Player Ratings. The Lions fullback will give Dixon – the second-ranked key forward at the Power and 219th overall – everything he can handle.
It's a big week for: Charlie Cameron
The Lions' excitement machine will love nothing more than to celebrate his 100th AFL game with a huge victory at his former home ground. Cameron showed glimpses of his potential when he played at Adelaide Oval every second week, but the former Crow has taken his game to another level at the Lions.
Big call: After being well held by Harris Andrews for most of the game, Charlie Dixon stands up with a huge goal with less than two minutes on the clock as the Power gets over the line.
Prediction: Power by two points
