Jackson Trengove will likely take over in the ruck against Simpson, with Young to take his place in defence.

A win for the visitors would see them replace Adelaide in eighth spot with one round remaining.

The Giants can’t move from sixth position on the ladder no matter the result.

Meanwhile, there are no late changes for Hawthorn's clash against Gold Coast at Marvel Stadium in Jarryd Roughead's farewell match.
