Wales international Bradley Roberts returns to start for the Dragons in their URC clash with the Stormers on Saturday.
The hooker had linked up late with Dai Flanagan's side after being part of the Wales squad this autumn, but goes straight into the starting XV as the Dragons head coach tinkers with his side after last weekend's 33-25 defeat to the Lions.
Max Clark starts at inside centre, Jordan Williams replaces David Richards on the wing and Rhodri Williams and JJ Hanrahan are the choices at half-back. In the pack, Roberts starts in the front-row, while Matthew Screech makes his first start since rejoining the Dragons on loan from Cardiff and Huw Taylor gets the nod at blindside flanker.
Flanagan said: "We are most certainly going up a level against the Stormers. Their squad is very strong. They had a lot of development players in the side against the Scarlets, but it didn't change the way they play.
"They have a DNA and they challenged the Scarlets a lot; they have line speed in defence and play a bit more with their back line than then opposition we faced last week.
"We are preparing for the very best Stormers team, and we have to be ready."
