Josh Adams returns to Cardiff's starting XV days ahead of Wayne Pivac's autumn squad announcement as the Arms Park outfit look to back up last weekend's derby win over the Scarlets with a victory against the Dragons on Saturday.
The Wales wing is back having missed the previous two matches through a minor groin injury, replacing Theo Cabango in the back-three. The only other change in the Cardiff backline sees Max Llewellyn replace Rey Lee-Lo in midfield.
In the pack, captain Josh Turnbull moves into the second-row after Lopeti Timani was ruled out with a calf injury, with Shane Lewis-Hughes taking his skipper's place on the blindside. On the bench, Wales internationals Dillon Lewis, Matthew Screech and James Botham all return, as does Aled Summerhill after an injury.
