What it means for Port Adelaide: Back-to-back losses to Collingwood and Adelaide have put the Power (4-4) back in the pack. A win against the SUNS is essential to get the Power some much-needed momentum.
What it means for Gold Coast: The SUNS (3-5) must regroup after their last-second one-point loss to Melbourne last weekend. The SUNS have been competitive most weeks but need to convert those near-chances into victories.
How Port Adelaide wins: Converting their chances inside the 50m arc. The Power kicked nine goals from 69 inside 50s in last weekend's Showdown loss to Adelaide, including an inaccurate 3.12 in the first three quarters.
How Gold Coast wins: Turning the game into a low-scoring affair. The SUNS have kicked 61, 73 and 59 points in their three wins this season. They don't have the offensive firepower to come out on top in a shootout.
The stat: The SUNS recorded their first win in club history with a three-point upset of Port Adelaide in round five, 2011. But the pendulum has swung back to the Power since then – winning the next nine meetings between the two clubs by an average margin of 44 points.
The match-up: Paddy Ryder v Jarrod Witts
While Ryder will split time with Scott Lycett in the ruck, his athleticism and tap work when he does go in the middle will be a big challenge for Witts. Ryder is the fifth-ranked ruck in the competition in the AFL Player Ratings, with Witts ranked 10th.
It's a big week for: Jack Hombsch
SUNS defender Jack Hombsch played 98 games for the Power before requesting a trade at the end of last season after falling out of their best 22. He will have a point to prove against his former club.
