PORT Adelaide vice-captain Hamish Hartlett is likely to miss the Power's clash with Essendon after struggling to recover from hamstring soreness.
Hartlett played in round one against St Kilda and had 24 disposals, but didn't play in the 58-point Showdown loss last Saturday.
Forward Jay Schulz may return after missing the Adelaide game with a back injury.
Schulz, 30, kicked 44 goals in 20 games last year.
Matt White has been placed on the long-term injury list with a pectoral injury, meaning he can't play football for eight weeks.
The club has not yet nominated a rookie to upgrade.
