The premiership duo are joined by ruckman Luke Lowden who will make his AFL debut, while Matt Spangher will also return.
David Hale will miss the trip to Tasmania, however, after failing to overcome a corked quad, while Will Langford, Jonathan Simpkin and Mitch Hallahan have been omitted.
Rioli missed just three weeks with a hamstring injury sustained in Round 8 but after training strongly both this week and last, he will return and add pace and excitement to Hawthorn’s team.
Spangher, meanwhile, returns after recovering from an ankle injury and will bolster Hawthorn’s big man stocks.
Ben Stratton (adductor) and Ben McEvoy (corked hamstring) haven’t yet recovered from injury and won’t fly to Tasmania.
