KEY defender Janelle Cuthbertson and midfielder Maria Moloney have both been added to Port Adelaide's injury list following Round 1.

Cuthbertson pulled up sore after suffering a knock to the torso from Adelaide's Rachelle Martin, which occurred during a marking contest in Saturday's Showdown.

The 33-year-old will be assessed throughout the week to determine her eligibility for selection.

Moloney is recovering from an ankle sprain sustained during a match scrimmage for non-selected players on Saturday morning.

She will serve the second game of her two-match ban this weekend but is expected to be available for Round 3.

Port Adelaide will name its side for this Saturday's game against Brisbane at 5:50pm ACST on Thursday.
