Port Adelaide has made a late change, less than half an hour before the bounce.
Karl Amon will miss tonight's clash with a knee injury.
Rhett Biglands spoke to an AFL official on the boundary and confirmed the news.
"Yes, the AFL official has just confirmed to us," he said on Triple M.
"Late change for Port Adelaide: Karl Amon is out of Port Adelaide's side and Jimmy Toumpas comes in after showing some stellar form in the SANFL."
Amon has struggled with a knee injury during the week.
Hawthorn has gone in unchanged.
