PORT ADELAIDE has made a change to its side to face Brisbane on Sunday afternoon. 

Dan Houston will not play due to sickness (virus).

He will be replaced by midfield bull Sam Powell-Pepper. 

Motlop, SPP, Rockliff and Howard will start on the bench. 

Brisbane has also made a late change, with Ben Keays coming in for Hugh McCluggage (hamstring tightness). 

First bounce is at 4.10pm ACST at Adelaide Oval.
