PORT ADELAIDE will be forced to make at least one change for its clash with Greater Western Sydney on Sunday afternoon.

Paddy Ryder suffered a low-grade hip-flexor strain in Port’s nine-point loss to Fremantle in Perth last weekend and is expected to miss 1-2 games.

The Power will also be sweating on the fitness of star forward Robbie Gray, who suffered a concussion in the early stages of the second half against the Dockers.

Jack Trengove again led the way in the SANFL collecting 26 touches, three marks, three inside 50s, and eight tackles.

Jarrod Lienert and Jasper Pittard were both impressive playing in the backline for the Magpies, each collecting 22 disposals despite the disappointing loss.

Meanwhile, Will Snelling continued his good season for the Magpies - the strong-bodied midfielder had 20 possessions and 11 tackles, and will be in the selection mix.

Port’s squad will be announced at 5.55pm ACST on Thursday evening.
