PORT ADELAIDE will be forced to make at least two changes from the side that lost to Brisbane by 48 points at Adelaide Oval last weekend.

Defender Ryan Burton and forward Brad Ebert will both miss this weekend’s clash with Richmond at the MCG, while co-captain Ollie Wines remains in doubt.

Dan Houston was a late withdrawal from the game against the Lions with a virus, and will come back into the side if fully recovered.

Matthew Broadbent had a game-high 38 disposals and 17 marks for the Magpies in the SANFL on the weekend against Adelaide, which will put him in the selection mix.

Fellow defender Jarrod Lienert was also very impressive in the Magpies’ 30-point win, collecting 34 touches, six marks and four tackles.

Midfielders Joe Atley (25 touches), Willem Drew (24) and Sam Mayes (24) were very good in the engine room, and will also be a chance.

Key forward Billy Frampton kicked six goals against the Crows in Port Pirie last weekend, but will not be available after accepting a two-match ban for rough conduct.

The final side will be announced on Thursday evening, ahead of a blockbuster clash with the Tigers on Saturday afternoon.
