PORT ADELAIDE has been forced to make a late change to its side to play Melbourne on Saturday afternoon.

Defender Matthew Broadbent was unable to recover from a bout of gastro suffered over the weekend in time for the Power's AFL Sir Douglas Nicholls Indigenous Round game against the Dees in Alice Springs.

He is replaced in the selected side by emergency Sam Gray.

Port Adelaide plays Melbourne at 1.40pm (ACST) on Saturday 28 May.
