PORT ADELAIDE could look to make a couple of changes to the side that was defeated by 25 points at the hands of the Western Bulldogs last weekend.

In the SANFL, Tom Rockliff produced a record-breaking performance against North Adelaide, collecting 57 disposals, 14 clearances, 12 tackles and seven marks.

Power utility Justin Westhoff was also brilliant with 37 touches and three goals, while midfield bull Sam Powell-Pepper (33 touches), defender Jarrod Lienert (28) and Paddy Ryder (34 hit-outs and two goals) were also in the best.

Inside midfielder Joe Atley continued his good SANFL form against the Roosters with 27 touches and 10 tackles, while Sam Mayes and Trent McKenzie were again influential players.

Speedy forward Aidyn Johnson hit the scoreboard with two goals, and Todd Marshall kicked one major among 15 disposals - on a day that was very difficult for key forwards.

The final teams will be announced on Thursday evening, ahead of a 4.05pm start to Showdown XLVII at Adelaide Oval on Saturday afternoon.
