Adelaide's Izak Rankine has kicked three goals in a 30-point win over arch-rivals Port Adelaide, with Power captain Connor Rozee under more injury concern.
Rankine also set up two other goals in the Crows' 12.6 (78) to 5.18 (48) win on Thursday night at Adelaide Oval as Rozee again failed to finish because of a hamstring concern.
Rozee also couldn't complete last week's win against St Kilda but the Power punted on the fitness of their skipper for the Crows game.
The playmaker was subbed out in the third term and Mitch Georgiades and Lachie Jones appeared to suffer leg injuries in a loss which leaves Port with a 5-3 win-loss record
The Crows move to 3-5 and hold overall boasting rights over Port: in 55 games between the SA rivals, Adelaide now have a 28-27 edge.
Adelaide led the entire game as midfielder Jake Soligo continued his rich form with 27 disposals.
Fellow on-ballers Matt Crouch (28 touches), Jordan Dawson (24) and Rory Laird (26) were busy and Darcy Fogarty (two goals) was a standout in attack.
Veteran Taylor Walker also booted two goals while Mark Keane and Josh Worrell were superb in defence.
Port vice-captain Zak Butters gathered a game-high 33 disposals and Miles Bergman (20 touches) and Brownlow medallist Ollie Wines (22) battled gamely.
Jason Horne-Francis (two goals) was damaging in spurts and Dan Houston (20 possessions) was accomplished at halfback.
Adelaide's Fogarty booted two early goals in a 90-second burst to set the tone for the Crows.
And when his veteran teammate Walker took possession at half-forward, had a bounce, and slotted from 50 metres, the Crows were 18-1 up.
Port's Charlie Dixon settled his side before two more Adelaide goals created a 23-point buffer.
The Power rallied with two late strikes - a Todd Marshall long-range effort reduced their deficit to eight points at quarter time.
Adelaide gradually edged further ahead in a low-scoring second term with Rankine and Lachlan Sholl scoring while keeping Port goal-less.
The Crows led by 19 points at halftime, 7.2 to 3.7, and again made another move in the third term.
After Walker booted his second goal, Rankine produced a trademark goal - from one step and a tight angle, he put Adelaide 31 points ahead.
The Power clawed one back through Horne-Francis but the Crows were still in command by 23 points at three quarter-time, 9.4 to 4.11.
Horne-Francis slotted his second to bring Port within 18 points but Adelaide then iced the victory with three consecutive goals.
