Last chance for in-form Dragons to stake Wales claim

"They need to keep on top of their form for the Wales coaches to keep viewing them."

Dragons were edged out 18-12 by Montpellier in the semi-finals of the Challenge Cup on Sunday and have a six-day turnaround to the fixture against Edinburgh.

Tiatia makes five changes to the starting line-up with wing Jared Rosser, scrum-half Rhodri Williams, tight-head prop Dillon Lewis, lock Seb Davies and blind-side flanker Harri Keddie starting.

Wainwright makes his final Rodney Parade appearance before his summer move to Leicester as 14th-placed Dragons attempt to finish above Welsh rivals Scarlets.

Edinburgh, who are fresh from URC wins against Zebre and Sharks, host Connacht after their Newport trip and could finish from 10th to 14th.

Sean Everitt's side have won just once on their travels this season - a 15-14 success at Benetton in round nine - but have a four-game winning streak against Dragons.

Edinburgh are boosted by the return of Lions wing Duhan van der Merwe, who has not played since January because of an ankle injury.

Loose-head prop Pierre Schoeman makes his 150th appearance for the club with back-row forward Magnus Bradbury set to reach the same milestone from the bench.
