Ben Castle gets his first start for the region since his return from the ruptured bicep he suffered in the pre-season friendly against Worcester and Danny Lydiate, who has been released from the Welsh squad for the weekend starts in the back row.
Steve Jones starts again at hooker with Duane Goodfield providing cover on the bench.
"We've rewarded those players who did well last weekend" said Dragons Head Coach Paul Turner. Although it's frustrating not to have our younger players available through international commitments, we were able to give opportunities to some of our senior squad last weekend and they made the most of them."
